Memory card

 A memory card is a form of storage device for films, photographs, and other data files. It provides both a volatile and non-volatile storage media for data from the inserted device. A flash memory is another name for it. It's often found in phones, digital cameras, computers, digital camcorders, gaming consoles, MP3 players, printers, and other electronic devices. Memory card technology is based on flash memory, which was pioneered by Fujio Masuoka at Toshiba in 1980. Toshiba went on to commercialise it in 1987.

Memory cards were first introduced about 1990, when digital cameras and mobile phones started to improve and become more advanced. Nowadays, having a mobile phone with a camera with a resolution of 5 megapixels is the norm, allowing users to shoot high-quality images. Mobile phones have a relatively limited internal storage space, usually about 10MB. As a result, memory cards are required to store data such as music, video, photographs, and other types of data.

PC cards, the first commercial memory card formats, were widely used in industrial applications to link I/O devices such as modems. Since 1994, various memory card types smaller than PC Card have been launched. The first card was CompactFlash, followed by SmartMedia and Miniature Card.

The SDcard was the first to be launched, followed by the MiniSD, MicroSD, MS Micro2, and Micro SDHC, all of which were built using the SDcard format. SanDisk was one of the earliest memory makers to recognise the need for storage. Memory cards were utilised in video game controllers such as the Xbox, GameCube, and Play Station, in addition as camcorders, phones, and cameras. Toshiba introduced the SmartMedia Card, a NAND-based flash memory card standard, as a replacement to the computer floppy disc in 1995. SmartMedia memory cards had storage capacities ranging from 2 MB to 128 MB, which is insufficient for today's photographs. A SmartMedia card was one of the smallest and thinnest of the early memory cards, consisting of a single NAND chip placed in a thin plastic card; since it was the smallest and thinnest memory card, it was susceptible to damage from bending. These memory cards were particularly popular in digital cameras and were widely utilised in portable devices.

In 2001, CF entered the professional digital camera market, and by 2005, SM had captured about half of the market. The format started to have issues as camera resolutions rose. Memory cards with a capacity of greater than 128 MB were unavailable, and SmartMedia cards were too big to be used. Toshiba eventually turned to smaller, higher-capacity SD cards in 1999.
