   High-capacity, high-speed standard using PCIe as interface Universal Flash Storage Card Extensions Samsung: UFS Card: 2016 >256 GB Packages the flash memory, currently soldered in shipping smartphones, into a removable card form factor. Uses the SCSI command set including queuing.

3. USB flash drive - Wikipedia

   en.wikipedia.org/wiki/USB_flash_drive

   A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc , and usually weighs less than 30 g (1 oz).

4. CompactFlash - Wikipedia

   en.wikipedia.org/wiki/CompactFlash

   CompactFlash IDE (ATA) emulation speed is usually specified in "x" ratings, e.g. 8x, 20x, 133x. This is the same system used for CD-ROMs and indicates the maximum transfer rate in the form of a multiplier based on the original audio CD data transfer rate, which is 150 kB/s.

   Determine the type, memory capacity and capabilities of the SD card; Command the card to use a different voltage, different clock speed, or advanced electrical interface; Prepare the card to receive a block to write to the flash memory, or read and reply with the contents of a specified block.

6. Universal Flash Storage - Wikipedia

   en.wikipedia.org/wiki/Universal_Flash_Storage

   Universal Flash Storage (UFS) is a flash storage specification for digital cameras, mobile phones and consumer electronic devices. [ 1 ] [ 2 ] It was designed to bring higher data transfer speed and increased reliability to flash memory storage, while reducing market confusion and removing the need for different adapters for different types of ...

7. Memory card - Wikipedia

   en.wikipedia.org/wiki/Memory_card

   The basis for memory card technology is flash memory. [2] It was invented by Fujio Masuoka at Toshiba in 1980 [3] [4] and commercialized by Toshiba in 1987. [5] [6] 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 ...

8. Flash memory - Wikipedia

   en.wikipedia.org/wiki/Flash_memory

   Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level depending on ...

9. Density (computer storage) - Wikipedia

   en.wikipedia.org/wiki/Density_(computer_storage)

   With the notable exception of NAND Flash memory, increasing storage density of a medium typically improves the transfer speed at which that medium can operate. This is most obvious when considering various disk-based media, where the storage elements are spread over the surface of the disk and must be physically rotated under the "head" in ...
