Varieties of memory cards and their applications.txt

Memory cards normally possess the qualities of smaller size, massive storage capacity, and so forth., and are frequently used as storage carriers in our each day lives. We need such little and high-capacity storage containers from mobile phones to cameras. Nowadays I'll give you an inventory of the memory cards usually used in life and their application areas.

Memory cards primarily incorporate MMC card, SD card, memory stick, PCIe flash memory card, XQD card, CF card, XD image card, SM card, M2 card, and so on.

MMC card (MultimediaCard) is translated into 'multimedia card'. Is actually a flash memory card standard. Mostly aimed at digital photos, music, mobile phones, PDAs, e-books, toys along with other items, its size is only 32mm × 24mm × 1.4mm, and the weight is only 1.5 grams. However, on account of the lack of support from consumer digital makers, you will discover not several products which can use MMC memory cards inside the digital solution industry.

The SD card (SecureDigital) is jointly created by Panasonic, Toshiba and SanDisk in Japan. The size is 32mm×24mm×2.1mm plus the weight is only two grams, however it has the characteristics of huge capacity, high data transmission rate and fantastic flexibility. The structure of the SD card can guarantee the safety of digital file transmission, and it really is also simple to reformat, so it includes a wide array of applications. Quite a few digital cameras use SD as a storage medium. This also makes the SD card the most widely employed memory card.

MiniSD is created from an SD card, and its performance will not be much different from a standard SD card. Like the SD card, the MiniSD card features a hardware information write protection switch to avoid the danger of accidental deletion of stored content material. On folder recovery software free download , the size of your MiniSD card is a lot more compact, only 21.5mm×20mm×1.4mm, which is 40% less than the SD card. It may be utilised using a unique adapter card and is fully compatible with standard SD card slots. On the other hand, one of the most important point is that the MiniSD card makes use of a low energy consumption design and style, so it can be a lot more suitable for mobile communication devices than the SD card. At present, it is mainly used in facts terminal devices including mobile phones, PDAs, and handheld computer systems.

TF card, also referred to as T-Flash card, complete name: TransFLash (aka: MicroSD), is actually a incredibly tiny flash memory card, jointly developed by Motorola and SANDISK. It has the benefits of getting small and active, mostly utilised in mobile phones, but using the increasing capacity, it gradually began to be made use of in a wider area. In the similar time, it can also be connected to an SD card slot with an adapter and features a large capacity. The full name from the memory stick is MemoryStick, which can be a mobile storage medium developed by Sony Corporation in Japan. This storage device looks like chewing gum, and has and features a quite high compatibility. Later, Sony decreased the volume to about 1/3 determined by the memory stick, and designed and manufactured the memory stick Duo. folder recovery is very convenient to be made use of in really little mobile phones and digital cameras, as well as numerous mp3 players and also other electronic products.

PCI-e flash memory card (PCI-Express) would be the most recent bus and interface common. Its original name was '3GIO'. PCIe is actually a high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices are allocated exclusive channel bandwidth. Shared sources, primarily supporting functions including active energy management, error reporting, end-to-end reliability transmission, hot swap and high-quality of service (QOS). The principle is depending on NAND flash memory.

SM (SmartMedia) card is actually a type of micro memory card, which is similar to SD card. Published by Toshiba Corporation in November 1995. SmartMedia makes use of a 22-pin interface and utilizes a physical format and a logical format. The physical format guarantees the compatibility amongst unique device models, which the method and manage vendors ought to obey. The physical format is according to the FAT standards of ATA and DOS files, so that it can be easier to exchange data amongst distinctive systems, however the configuration in the physical format will differ in page size, depending on the type of memory and the capacity on the memory card. As for the logical format, the DOS-FAT format is adopted, which is, the cylinder head sector parameters, the main sector, plus the partition. SmartMedia also has two functioning voltages of 3.3V and 5V, but it cannot assistance each voltages at the same time. Nevertheless, there are actually no merchandise that use SM memory cards inside the digital cameras launched right now. CF card (CompactFlash) was initially a data storage device for portable electronic devices. As a storage device, it revolutionaryly makes use of flash memory. It was very first made by SanDisk Corporation in 1994 and established relevant specifications. At present, its physical format has been adopted by lots of devices. Nonetheless, the capacity on the CF card is restricted, and its capacity can not preserve up with the improvement of digital camera pixels. Compared with other kinds of memory cards, the volume is reasonably large. Furthermore, the operating temperature is generally 0-40 degrees Celsius, which limits its efficiency.

XQD memory card is usually a kind of memory card developed by Sony. Its volume is substantially smaller sized than the present CF card, only about half its size. However, the XQD memory card retains the CF card for quickly and stable reading. In addition, the XQD memory card also utilizes an upgradeable high-performance interface. Its reading and writing speed reached 125 megabits per second.

The XD-PictureCard (xD) card is a memory card jointly launched by Olympus and Fuji. It has an particularly compact type aspect, with an external size of 20mm×25mm×1.7mm and a weight of only 2 grams. Its reading and writing speed can attain 5MB/S and 3MB/S. The earliest XD card was mainly used in Olympus and Fuji digital camera merchandise. While its functionality can meet the significant information volume and also the power consumption is reduced, the somewhat high cost significantly limits the development with the XD card. At present, Olympus and Fuji digital cameras no longer only use XD cards as storage media. The M2 card can be a new memory card MemoryStickMicro (M2) jointly launched by Sony and SanDisk, which was launched in March 2006. This M2 card utilizes ultra-small circuit design and style, particularly for large-capacity, small-volume mobile storage demands, weighing only 16 grams, the external dimensions are only 15 × 12.five × 1.2mm, the volume is about a quarter with the memory stick ProDuo.
