Flash Drives
A flash drive is a portable computer drive that uses flash memory. Flash drives are the larger memory modules consisting of a number of flash chips. A flash chip is used to read the contents of a single cell, but it can write entire block of cells. They connect to a USB port and function as a folder. Specific flash drive types Memory cards: * Flash memory-based CompactFlash (CF) card (including CFast card) and XQD card (Note: some other types of CF and XQD card are not flash memory-based) * Memory Stick (MS) * MultiMediaCard (MMC) * Secure Digital card (SD, SDHC, SDXC) * SmartMedia card (SM) * xD-Picture Card (xD) Other: * Solid-state drive, SSD, using flash memory (a few SSDs use DRAM or MRAM) * USB flash drive (UFD) See also * Flash memory Flash memory is an Integrated circuit, electronic Non-volatile memory, non-volatile computer memory storage medium that can be electrically erased and reprogrammed.

Flash Memory
Flash memory is an Integrated circuit, electronic Non-volatile memory, 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 gate, NOR and NAND gate, NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level, depending on whether the state of the bit line or word lines is pulled high or low; in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented by Fujio Masuoka at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire devi ...

Memory Card
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 Neo Geo. They allow adding memory to such devices using a card in a socket instead of protruding USB flash drives. Common types of flash memory card include SD cards (including microSD), Sony's Memory Stick and CompactFlash. , SD cards are the most common type of memory cards. History The basis for memory card technology is flash memory. It was invented by Fujio Masuoka at Toshiba in 1980 and commercialized by Toshiba in 1987. 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. Several competing and inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CompactFlash
CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994. CompactFlash became one of the most successful of the early memory card formats, surpassing Miniature Card and SmartMedia. Subsequent formats, such as MMC/ SD, various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS, are faster, but physically larger and more costly. CompactFlash's popularity is declining as CFexpress is taking over. As of 2022, both Canon and Nikon's newest high end cameras, e.g. the Canon EOS R5, Canon EOS R3, and Nikon Z 9 use CFexpress cards for the higher performance required to record 8K video. Traditional CompactFlash cards use the Parallel ATA interf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XQD Card
The XQD card is a memory card format primarily developed for flash memory cards. It uses PCI Express as a data transfer interface. The format is targeted at high-definition camcorders and high-resolution digital cameras. It offers target read and write speeds from 1 Gbit/s to about 5 Gbit/s and storage capabilities beyond 2 TiB. The cards are not backward compatible with CompactFlash or CFast cards, and despite the name similarity, has no connection with the xD-Picture Card. XQD and CFast were both designed as a replacement of the 1994 CompactFlash standard. The format was first announced in November 2010 by SanDisk, Sony and Nikon, and was immediately picked up by the CompactFlash Association for development. The final specification was announced in December 2011. XQD version 2.0 was announced in June 2012, featuring support for PCI Express 3.0 with transfer rates up to 8 Gbit/s (1 GB/s). On 7 September 2016 the CFA announced the successor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory Stick
The Memory Stick is a removable flash memory, flash memory card format, originally launched by Sony in late 1998. In addition to the original Memory Stick, this family includes the Memory Stick PRO, a revision that allows greater maximum storage capacity and faster file transfer speeds; Memory Stick Duo, a small-form-factor version of the Memory Stick (including the PRO Duo); the even smaller Memory Stick Micro (M2), and the Memory Stick PRO-HG, a high speed variant of the PRO to be used in high-definition video and still cameras. As a proprietary format, Sony exclusively used Memory Stick on its products in the 2000s such as Cyber-shot digital cameras, Handycam digital camcorders, Sony Ericsson mobile phones, WEGA and Bravia (brand), Bravia TV sets, VAIO PCs, digital audio players, and the PlayStation Portable game console, with the format being licensed to a few other companies early in its lifetime. With the increasing popularity of SD card, Secure Digital around 2010, Sony st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MultiMediaCard
MultiMediaCard, officially abbreviated as MMC, is a memory card standard used for solid-state storage. Unveiled in 1997 by SanDisk and Siemens, MMC is based on a surface-contact low-pin-count serial interface using a single memory stack substrate assembly, and is therefore much smaller than earlier systems based on high-pin-count parallel interfaces using traditional surface-mount assembly such as CompactFlash. Both products were initially introduced using SanDisk NOR-based flash technology. MMC is about the size of a postage stamp: 32 mm × 24 mm × 1.4 mm. MMC originally used a 1- bit serial interface, but newer versions of the specification allow transfers of 4 or 8 bits at a time. MMC can be used in many devices that can use Secure Digital (SD) cards. MMCs may be available in sizes up to 16 gigabytes (GB). They are used in almost every context in which memory cards are used, like cellular phones, digital audio players, digital cameras, and ...

Secure Digital
Secure Digital (SD) is a proprietary, non-volatile, flash memory card format developed by the SD Association (SDA). Owing to their compact size, SD cards have been widely adopted in a variety of portable consumer electronics, including digital cameras, camcorders, video game consoles, mobile phones, action cameras, and camera drones. The SD format was introduced in August 1999 by SanDisk, Panasonic (then known as Matsushita), and Kioxia (then part of Toshiba). It was designed as a successor to the MultiMediaCard (MMC) format, introducing several improvements aimed at enhancing usability, durability, and performance, which contributed to its rapid emergence as an industry standard. To manage the licensing and intellectual property rights related to the format, the three companies established SD-3C, LLC. In January 2000, they also founded the SDA, a non-profit organization dedicated to developing and promoting SD card standards. As of 2023, the SDA includes approximatel ...

SmartMedia
SmartMedia is an obsolete flash memory, flash memory card standard owned by Toshiba, with capacities ranging from 2 MB to 128 MB. The format mostly saw application in the early 2000s in digital cameras and audio production. SmartMedia memory cards are no longer manufactured. History The SmartMedia format was launched in the summer of 1995 to compete with the Miniature Card, MiniCard, CompactFlash, and PC Card formats. Although memory cards are nowadays associated with digital cameras, digital audio players, Personal digital assistant, PDAs, and similar devices, SmartMedia was pitched as a successor to the computer floppy disk. Indeed, the format was originally named Solid State Floppy Disk Card (SSFDC), and the physical design resembles a miniature 3.5" floppy disk. The SSFDC forum, a consortium aiming to promote SSFDC as an industry standard, was founded in April 1996, consisting of 37 initial members. A SmartMedia card consists of a single NAND flash chip embedded in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XD-Picture Card
The xD-Picture Card is an obsolete flash memory card format, used in digital cameras made by Olympus company, Olympus, Fujifilm, and Kodak between 2002 and 2009. xD cards were manufactured with capacities of 16 megabyte, MB up to 2 gigabyte, GB. The standard was phased out in the late 2000s in favour of the SD card, which had been its primary competitor. History The cards were developed by Olympus company, Olympus and Fujifilm, and introduced into the market in July 2002. Toshiba, Toshiba Corporation and Samsung Electronics manufactured the cards for Olympus and Fujifilm. xD cards were sold under other brands, including Kodak, SanDisk, PNY Technologies, PNY, and Lexar, but were not branded with the respective companies' logos, except for Kodak. Previously, xD competed primarily with Secure Digital (SD) cards, CompactFlash (CF), and Sony's Memory Stick. Because of its higher cost and limited usage in products other than digital cameras, xD lost ground to SD, which is b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
