A memory card is an electronic data storage device used for storing digital information, typically using flash memory. These are commonly used in digital portable electronic devices, such as Digital cameras as well as in many early games consoles such as the Nintendo Wii. They allow adding memory to such devices using a card in a socket instead of protruding USB flash drives.[1]
Common types of flash memory card include SD cards (including microSD), Sony's Memory Stick and CompactFlash. However, SD cards are by far the most common type of memory cards nowadays[citation needed].

The development of memory cards was driven in the 1980s by the need for an alternative to floppy disk drives that had lower power consumption, had less weight and occupied less volume in laptops. Some were also marketed as a lower cost alternative to ROM cartridges.[7] Several competing and incompatible memory card formats were developed by several vendors,[8] such as for example the Bee Card, Astron SoftCards,[9] Sega Cards, NEC UltraLite memory cards,[10][11] and the Mitsubishi Melcard which came in variants using 60 and 50 connector pins. The Sega Card was developed as a cheaper alternative to game cartridges.[12] Some memory cards were used for memory expansion in laptops.[13][14][15]
JEIDA, the Japan Electronic Industry Development Association, began to work on a standard for memory cards in 1985, and developed the JEIDA memory card in 1986.[16]The Personal Computer Memory Card International Association (PCMCIA) was an industry association created in 1989 to promote a standard for memory cards in PCs, and worked closely with JEIDA, adopting their 68 pin connector design. The specification for PCMCIA type I cards, later renamed PC Cards, was first released in 1990, and unified the JEIDA memory card standard with the PC Card standard.[15][17] This format later included support for other devices besides memory cards.[17] PC Card was among the first commercial memory card formats to come out, but is now mainly used in industrial applications and to connect I/O devices such as modems.
Some early memory cards used SRAM as a storage medium, which required a lithium battery to keep the contents in the SRAM. These cards were faster than their flash counterparts. Some of the first PCMCIA cards had capacities of 1 to 5 MB and cost US$100 per MB.[18] Other early cards such as the Bee Card contained non-modifiable ROM, Write once read many EPROM or rewriteable EEPROM memory.[19] In 1992, SanDisk introduced FlashDisk, a PCMCIA card and one of the first memory cards that did not require battery power to retain its contents, as it used flash memory.[20][18]
Since 1994, a number of memory card formats smaller than the PC Card arrived. The first one was CompactFlash and later SmartMedia and Miniature Card. The desire for smaller cards for cell-phones, PDAs, and compact digital cameras drove a trend that left the previous generation of "compact" cards looking big. In 2000 the SD card was announced. SD was envisioned as a single memory card format for several kinds of electronic devices, that could also function as an expansion slot for adding new capabilities for a device.[21] In 2001, SmartMedia alone captured 50% of the digital camera market and CF had captured the professional digital camera market.
However, by 2005, SD and similar MMC cards had nearly taken over SmartMedia's spot, though not to the same level and with stiff competition coming from Memory Stick variants, as well as CompactFlash. In industrial and embedded fields, even the venerable PC card (PCMCIA) memory cards still manage to maintain a niche, while in mobile phones and PDAs, the memory card has become smaller.
Initially memory cards were expensive, costing US$3 per megabyte of capacity in 2001;[22] this led to the development of miniaturized rotating disk memory devices such as the Microdrive, PocketZip and Dataplay. The Microdrive had higher capacities than memory cards at the time. All three concepts became obsolete once flash memory prices became lower and their capacities became higher by 2006.[20]
Since 2010, new products of Sony (previously only using Memory Stick) and Olympus (previously only using XD-Card) have been offered with an additional SD-Card slot.[23] Effectively the format war has turned in SD-Card's favor.[24][25][26]
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 would not 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.[29][30] 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.
Home consoles now commonly use hard disk drive storage for saved games and allow the use of USB flash drives or other card formats via a memory card reader to transport game saves and other game information. Though some consoles have implemented cloud storage saving, most portable gaming systems still rely on custom memory cartridges to store program data, due to their low power consumption, smaller physical size and reduced mechanical complexity.
There are several line to follow here:
Is the card you are inserting a Micro SD card with an adapter? If so, they do not work well with Canon and many other camera brands. You should always use a full-size SD card.
Is the card a reputable manufacturer and purchased form a reputable store - lots of places on the web sell counterfeit cards, or ones that were rejected in manufacture.
Did the card work in other devices?
I'm using the PowerShot A510 and I've tried several card types. A 16 gb, 32, and even a 128 but every single time it says "Memory Card Error" and I don't know how to fix this. I really want to use this digi cam for my next trip so if anyone could tell me the problem and give me advice please do so!!
Are you using full-size memory cards or microSD with an adapter? If you're having issues with multiple cards, it's probably the card reader in the camera. If not already done, perform a full settings reset and retry. If the behavior continues, the slot might be damaged or the camera is malfunctioning.
The 128 is a microSD with an adaptor but the 32 and 16 were sandisk cards. I checked the manual and it said to use 2gb sd cards instead but I don't know if that's true or not. And I dont know how to perform a full settings reset.. I've never had a camera like this before
The camera was released back in 2004. So at this point, I would recommend looking at a much newer model. Used or refurbished point-and-shoots that would be able to use SDXC cards (do though always use full-sized cards). Or, if you have a smart phone, use that during your trip instead.
Respectfully, the A510 is a 3.2MP camera and cannot compare with a decent cell phone as RS-EOS mentioned. I'd probably abandon trying to find a compatible card for this 19 yr old camera.
2 and 3. I don't have an actual photo right now and will not be able to take the test because I'm on vacation. I'm pretty much sure that my sd cards are not fake as I bought it from samsung retail store and did the test before I inserted it in the cameras. Also, my other CCTVs with other brands uses the same sd card without issues at all. Recording with tapo is good, quality is great, not lagging during playback. That's the only issue I'm getting every after auto reboot.
@aadesilva My camera messed my NEW SD CARD SAMSUNG 128GB and I cannot write any data, format or delete data from it. The camera recognized the card but was not able to write other files. I hope you are not encrypting our SD cards to force us to buy CLOUD Services, right?
yes my app is up to date. Unfortunately, I thought I could provide you but it's mounted atop and can't reach it by regular ladder. But as previously mentioned, playback and recording is good. If it's fake, I would have gone into a problem as other non tapo devices are using the same sd card without issues.
I have been using 1212s for 4 years or so now, and have never had an issue.
Today I grab one and try to put a program in it and it gives me a "access to memory card denied" and below it " The memory card is protected from write access" however there is no memory card installed. I have used this program a few times now and never needed a card.
I then tried a new project, I only put the 1212 in it, and one line of code --/i0.0/------(Q0.0)--
And I get the same error.
Pulled another one off the shelf, and program loads just fine in that one.
Problem Solved!!
I contacted Tech Support. If you look inside the memory card slot, there is a little pin way down inside, on the left. It gets pushed in when you put a memory card into the slot, and makes a contact letting the PLC know the card is there. I had to stick a tiny screwdriver in there and pry that pin out to the right a hair. This fixed it. 152ee80cbc
