MicroSD
Secure Digital (SD) is a proprietary hardware, proprietary, non-volatile memory, 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 Unmanned aerial vehicle, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SD Association
The SD Association (SDA) is an American nonprofit organization that sets standards for the SD memory card format. It was founded in January 2000 by SanDisk, Panasonic (then Matsushita), and Toshiba. By 2010, the SDA had about 1,000 member companies involved in designing and developing SD standards. Thousands of device models and products across many categories incorporate the small, removable memory cards. The SD Association develops industry standards that define successive generations of SD cards and guide manufacturers in product development. This approach has made the SD memory card the most widely used removable memory card form factor in the industry. SD standards "SD memory card" and "SD host device" are the umbrella descriptions for any memory card or device built to SD standards. The SDA does not manufacture, market or sell any product. It exists solely to create industry standards and promote the adoption, advancement and use of SD standards. These standards are ad ...

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 ...

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 ...

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] |
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] |
Samsung Galaxy S III

Action Camera
An action camera or action cam is a digital camera designed for recording action while being immersed in it. Action cameras are therefore typically compact, rugged, and waterproof at the surface level. They typically use CMOS image sensors, and can take photos in burst mode and time-lapse mode as well as record high-definition video (as of 2019, mid-range to high-end action cameras can record 4K resolution, 4K video at 60 frame rate, fps). Slow-motion video recording at 120 or 240 fps is also a common feature. Overview The camera is typically worn or mounted in such a way that it can shoot from the point of view of the shooter. Some examples of common places to mount an action camera are on a hat or helmet, on the chest, or on the handlebars of a bike or similar vehicle. They may also be mounted on a tripod or on a monopod for handheld use. An action camera is usually designed to require minimal interaction once recording has begun, as this allows continuous capture of the ...

Memory Density
Density is a measure of the quantity of information bits that can be stored on a given physical space of a computer storage medium. There are three types of density: length (''linear density'') of track, area of the surface (''areal density''), or in a given volume (''volumetric density''). Generally, higher density is more desirable, for it allows more data to be stored in the same physical space. Density therefore has a direct relationship to storage capacity of a given medium. Density also generally affects the performance within a particular medium, as well as price. Storage device classes Solid state media Solid state drives use flash memory to store non-volatile media. They are the latest form of mass produced storage and rival magnetic disk media. Solid state media data is saved to a pool of NAND flash. NAND itself is made up of what are called floating gate transistors. Unlike the transistor designs used in DRAM, which must be refreshed multiple times per second, ...
