Jump up ^ A. H. Johnston, “Space Radiation Effects in Advanced Flash Memories” Archived 4 March 2016 at the Wayback Machine.. NASA Electronic Parts and Packaging Program (NEPP). 2001. “… internal transistors used for the charge pump and erase/write control have much thicker oxides because of the requirement for high voltage. This causes flash devices to be considerably more sensitive to total dose damage compared to other ULSI technologies. It also implies that write and erase functions will be the first parameters to fail from total dose. … Flash memories will work at much higher radiation levels in the read mode. … The charge pumps that are required to generate the high voltage for erasing and writing are usually the most sensitive circuit functions, usually failing below 10 krad(SI).”

Initiating the GameCube’s design in 1998, Nintendo partnered with ArtX (then acquired by ATI Technologies during development) for the system logic and the GPU,[9] and with IBM for the CPU. IBM designed a PowerPC-based processor for the next-generation console, known as Gekko, which runs at 485 MHz and features a floating point unit (FPU) capable of 1.9 GFLOPS. Designed at 0.18 microns and described as “an extension of the IBM Power PC architecture”, Gekko features IBM’s reportedly then-unique copper-based chip manufacturing technology.[8] Codenamed “Flipper”, the GPU runs at 162 MHz and, in addition to graphics, manages other tasks through its audio and input/output (I/O) processors.[33][34][35][36]

On the left side, there may be a write-protection notch. If the notch is omitted, the card can be read and written. If the card is notched, it is read-only. If the card has a notch and a sliding tab which covers the notch, the user can slide the tab upward (toward the contacts) to declare the card read/write, or downward to declare it read-only. The diagram to the right shows an orange sliding write-protect tab in both the unlocked and locked positions.
Ok, don’t know why I’m doing this now but I bought it back in 2013 when I was 11. It’s a cheap price but with that you’ll expect some downsides. For example, (I still have mine by the way.) With my memory card you’ll need to push it in with force not because it’s big (its a perfect size) but because it has trouble reading it. It’ll constantly not recognize until you find the sweet spot. You won’t be moving the gamecube around anyway so I think it’s a pretty good deal. But still, could be been just a tiny bit better.
However, SD is much more open than Memory Stick, for which no public documentation nor any documented legacy implementation is available. All SD cards can be accessed freely using the well-documented SPI bus.

Some consumer-grade flash memory cards are used by companies to cache reads and writes with hybrid flash storage. Enterprise MLC is an MLC NAND variant with enhanced write cycles compared to consumer-grade MLC. Some newer enterprise SSDs use triple-level cell NAND flash, which stores three data bits per each flash cell. SSDs made with 3D NAND represent the next evolution. IBM, Samsung and Toshiba produce and market SSDs with 3D NAND, in which flash memory cells are stacked atop one another in vertical layers.
The company is environmentally-conscious and emphasizes conserving natural resources to employees and customers through its GREEN initiatives. In addition, IOGEAR has partnered with Trees for the Future to plant one tree for every product purchased on its Web site or by members of its GREEN initiative partner program.
The microSD format was made by the company SanDisk. It was first called T-Flash, and then TransFlash, before being named microSD when it started to be used by the SD Card Association (SDA). Other flash card formats approved by the SDA include miniSD and standard SD card.
The GameCube launched in Japan on September 14, 2001.[27] Approximately 500,000 units were shipped in time to retailers.[28] The console was scheduled to launch two months later in North America on November 5, 2001, but the date was pushed back in an effort to increase the number of available units.[29] The console eventually launched in North America on November 18, 2001, with over 700,000 units shipped to the region.[30] Other regions followed suit the following year beginning with Europe in the second quarter of 2002.[31]
The write speed describes how fast images can be saved onto a card, which is important when shooting bursts of images in continuous shooting mode, HD video or when using high resolution cameras that shoot particularly large files.
When it comes to flash memory cards, there are three aspects you need to consider: physical format, size, and speed. Each of the three variables has its own set of classes, so you can have anything from a 1GB Class 2 microSD card to a 32GB UHS-1 SDXC card. We’ll explore the distinctions below.
Store up to 32GB of your favorite photos, videos and music on this SanDisk Ultra microSDHC memory card that offers Class 10 video recording capability and up to 30MB/sec. read speed for fast data transfer.

All SD cards let the host device determine how much information the card can hold, and the specification of each SD family gives the host device a guarantee of the maximum capacity a compliant card reports.
A memory card, flash card or memory cartridge is an electronic flash memory data storage device used for storing digital information. These are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptop computers, tablets, PDAs, portable media players, video game consoles, synthesizers, electronic keyboards, and digital pianos.
Nintendo developed stereoscopic 3D technology for the GameCube, and one launch game, Luigi’s Mansion, supports it. However, the feature was never enabled outside of development. 3D televisions were not widespread at the time, and it was deemed that compatible displays and crystals for the add-on accessories would be too cost-prohibitive for the consumer.[43][44][45] Another unofficial feature are two audio Easter eggs that can be invoked when the console is turned on. When the power is activated with the “Z” button on the Player 1 controller held down, a more whimsical startup sound is heard in place of the standard one. With four controllers connected, holding down the “Z” button on all four simultaneously produces a “ninja-like” tune at startup.[46]
Hope in the future that Amazon punishes vendors who ship inferior, counterfeit, or products different than described or pictured. Right now, the only way I see to determine if this might be the case is to S L O W L Y read the 1 and 2 Star reviews for a product. Four or maybe even two years ago, you could comfortably make a purchase based on 4-Stars or above. No more – especially on these commodity products where confusion exists regarding product specifications. [On this product alone: SD vs. SDXC vs. SDHC; Suitability of Capacity; Choice of writing speed for application. For in-depth information see SDCard dot ORG] An overall rating is NO LONGER a sufficient criterion for a purchasing decision since many of these commodity type products have their reviews gamed by paid reviewers.
SD cards are not the most economical solution in devices that need only a small amount of non-volatile memory, such as station presets in small radios. They may also not present the best choice for applications that require higher storage capacities or speeds as provided by other flash card standards such as CompactFlash. These limitations may be addressed by evolving memory technologies, such as the world’s highest capacity SanDisk Ultra 200GB microSD released in 2015.[89]
The Kingston had read and write speeds of 159 MB/s and 127 MB/s, respectively, during our SD card test. In our microSD card test, it had expected read and write speeds of 83 MB/s and 69 MB/s. It was a bit slower when reading and writing to a CF card, with speeds of 127 MB/s and 107 MB/s.
I’ve long been a fan of Sandisk, and have faithfully used their compact flash memory cards in all my digital cameras, so imagine my surprise to have two 16 GB and two 32 GB cards fail in two different Samsung Galaxy SIII phones so far, taking all data with them. The cards cannot be accessed or formatted, either in the phone or on the computer. I’ve finally contacted Sandisk support, but after reading a lot of review on the web concerning this issue (and trying all the various workarounds posted), I’m not confident that Sandisk will be able to help me. There frankly should be NO WAY for an SD interface to make a card unusable, short of physically destroying it with overvoltage, period. I’m an embedded systems engineer (30+ years experience) and there is NO EXCUSE for Sandisk cards failing like this, unless the phone is doing something evil electrically to them. Please beware, and back up your files often, because it WILL FAIL eventually.
Look no further than this guide for your NAND flash memory essentials. Your copy includes an in-depth breakdown of SLC, MLC and TLC NAND, a performance and cost comparison of NAND vs. DRAM and NOR, and how the NAND flash shortage affects SSD supply and pricing.
Due to its relatively simple structure and high demand for higher capacity, NAND flash memory is the most aggressively scaled technology among electronic devices. The heavy competition among the top few manufacturers only adds to the aggressiveness in shrinking the design rule or process technology node.[31] While the expected shrink timeline is a factor of two every three years per original version of Moore’s law, this has recently been accelerated in the case of NAND flash to a factor of two every two years.
Video Speed Class is defined to answer a demand for high resolution and high quality 4K8K video recording and it also has an important feature to support next generation flash memory such as 3D NAND. Furthermore, as it covers speed of HD(2K) video, it is possible to integrate into Video Speed Class from now on.
Many personal computers of all types, including tablets and mobile phones, use SD cards, either through built-in slots or through an active electronic adapter. Adapters exist for the PC card, ExpressBus, USB, FireWire, and the parallel printer port. Active adapters also let SD cards be used in devices designed for other formats, such as CompactFlash. The FlashPath adapter lets SD cards be used in a floppy disk drive.
The earliest commercially designed SSDs were made with single-level cell (SLC) or multi-level cell (MLC) flash. SLC uses a high grade of flash media to provide performance and endurance, but it typically costs twice as much as MLC flash.
Neither the Kanex USB-C Card Reader nor the Plugable USB Type-C Flash Memory Card Reader supports CF cards. Both of them are larger and more expensive than the Cable Matters model we recommend, lack indicator lights, and have an extra Memory Stick slot that most people don’t need.
It is unclear how long flash memory will persist under archival conditions – i.e., benign temperature and humidity with infrequent access with or without prophylactic rewrite. Anecdotal evidence[specify] suggests that the technology is reasonably robust on the scale of years.[citation needed] Datasheets of Atmel’s flash-based “ATmega” microcontrollers typically promise retention times of 20 years at 85 °C (185 °F) and 100 years at 25 °C (77 °F).[78]
NOTE: As other buyers state, this item say’s Wii memory card on the packaging it comes in. This memory card is actually for a system called Nintendo GameCube. It does work on the Wii but only to save Nintendo Gamecube Games. If you’re looking for a Wii memory card for Wii games, that would an SD card you’re looking for.
4) Write speed is very quick from PC to this card. Bursts of over 30 MB/s with an average around 10-15 MB/s. Faster than the Cruzer Flash Drives SanDisk Cruzer Fit 16 GB x2 = 32GB USB Flash Drive SDCZ33-016G-B35-2PK w/ Everything But Stromboli (TM) Lanyard I reviewed elsewhere, but the utility of this SDHC card for moving files is limited by equipment that does not have a built-in card reader.
At the 2000 Consumer Electronics Show (CES) trade show, the three companies announced the creation of the SD Association (SDA) to promote SD cards. The SD Association, headquartered in San Ramon, California, United States, started with about 30 companies and today consists of about 1,000 product manufacturers that make interoperable memory cards and devices. Early samples of the SD Card became available in the first quarter of 2000, with production quantities of 32 and 64 MB cards available three months later.
Four-bit SD bus mode: Uses extra pins plus some reassigned pins. This is the same protocol as the one-bit SD bus mode which uses one command and four data lines for faster data transfer. All SD cards support this mode. UHS-I and UHS-II require this bus type.
SD cards are also available in various speeds. If you’re using a point-and-shoot digital camera or a standard-definition pocket camcorder, speed class won’t matter much. If you’re shooting high-resolution RAW photos with a digital SLR, however, you need a quick card to take more than two or three shots at a time. SD cards are generally described by their Speed Class, ranging from Class 2 (slowest) to Class 10 (fastest). There’s also a separate, even faster category called UHS Class 1 (for Ultra High Speed), but most current devices can’t use them.
The trademarked SD logo was originally developed for the Super Density Disc, which was the unsuccessful Toshiba entry in the DVD format war. For this reason the D within the logo resembles an optical disc.
Well I really didn’t think this topic would generate such intense controversy. I thought it would be relativley straightforward and easy to find out the answer, but I guess things are more complicated than that. Hopefully we’ll get an official comment from Nintendo about it one or another. I personally don’t care if they discontinue it, I’m not going to be offended by that decision, I just wish they were more upfront about it.
Version 5.0 was announced in February 2016 at CP+ 2016, and added “Video Speed Class” ratings for UHS cards to handle higher resolution video formats like 8K.[17][18] The new ratings define a minimum write speed of 90 MB/s.[19][20]
We appreciate your interest in the Nintendo GameCube.  At this time, we haven’t announced any immediate plans to discontinue the sale and distribution of this system, or the games available for it.  In fact, we still have a handful of software titles being developed for the Nintendo GameCube.  For the latest news and information on this system, as well as other Nintendo-related products, please keep an eye on the news section of our website (
NVDIMM-P combines the functionality of NVDIMM-F and NVDIMM-N on one module. The nonvolatile memory is allocated in two ways. Part of it provides persistence to DRAM, while the remainder is available as block storage.
Many older video game consoles used memory cards to hold saved game data. Cartridge-based systems primarily used battery-backed volatile RAM within each individual cartridge to hold saves for that game. Cartridges without this RAM may have used a password system, or wouldn’t save progress at all. The Neo Geo AES, released in 1990 by SNK, was the first video game console able to use a memory card. AES memory cards were also compatible with Neo-Geo MVS arcade cabinets, allowing players to migrate saves between home and arcade systems and vice versa.[7] Memory cards became commonplace when home consoles moved to read-only optical discs for storing the game program, beginning with systems such as the TurboGrafx-CD and Sega-CD.

Bought this for me and my wife shortly after we bought a GameCube (to relive our childhood) a little less than 2 years ago. So far it has worked flawlessly with all games played, and is not even close to filling up. Item received was slightly different in shape than the picture advertised, but that is purely aesthetic.
The ShippingPass assortment is continually being optimized. Products are added and removed for lots of reasons, but the main reason is to show items that we’re 100% sure we can deliver within the promised timeline.
Like most memory card formats, SD is covered by numerous patents and trademarks. Royalties for SD card licences are imposed for manufacture and sale of memory cards and host adapters (US$1,000/year plus membership at US$1,500/year), but SDIO cards can be made without royalties.

If you are interested in an SD card for a DSLR, look at something like the Lexar Professional 600x 32GB SDHC UHS-I Flash Memory Card LSD32GCRBNA600. Since switching to the C10/U1 Lexar, I’ve been infinitely more happy with my camera. The Sandisk C4 32GB remains in my point and shoot, where it’s better suited.
Getting yourself in a memory card muddle and not sure which card to buy? We look at memory card speeds and the fastest memory card on the market to help explain the differences so you can find out what’s the best card for you.
I have had the same problem with my Dell XPS L502x but the SD card reader will read the slow cards 4gb but when I put a 32 GB xtream it will not read so I have to use a USB card reader , I also have trouble now with the integrated web-cam this will not work through the Windows applications but have done a test online and it works, I have tried bios upgrades and there are no updates on the drives so like we all have been left high and dry !! 
The Hyperdrive 3-in-1 Connection Kit gave us SD read and write speeds of 20 MB/s, though we should have been getting at least 80 MB/s on a UHS-I connection. And its design obstructs other plugs—most notably blocking the power plug on a Dell XPS 13, and the only other port on the MacBook Pro (13-inch, late 2016, Two Thunderbolt 3 Ports).
Official pin numbers for each card type (top to bottom): MMC, SD, miniSD, microSD. This shows the evolution from the older MMC, on which SD is based. NOTE: This drawing doesn’t show 8 new UHS-II contacts that were added in spec 4.0.
