Memory card are very small in size, re-recordable, and able to retain data without power. We can carry them easily anywhere with us but it is very small in size that there are more risks of losing memory card device.

History

PC Cards (PCMCIA) were introduced among first commercial memory card formats these were considered as the type of I cards and were first come out in the 1990s, but now they are very rare for the common use they are mainly use in industrial applications and to connect Input and Output devices such as modems. In 1990s, large number of devices similar to memory card formats which were smaller than PC Card arrived, including Compact Flash, Smart Media, and Miniature Card. The introduction of hand held device drove the desire for smaller cards for cell-phones, PDAs, and compact digital cameras introduced a trend that left the previous generation of "compact" cards looking big. Smart Media and Compact Flash had been very successful in digital cameras. In 2001 Smart Media alone captured 50% of the digital camera market and Compact Flash had a strong hold on professional digital cameras. In 2005, SD/MMC had completely overlapped the place of Smart Media. However, this SD/MMC did not compete at the same level but give a tough competition to Memory Stick variants and CompactFlash as well. In industrial fields, venerable PC card (PCMCIA) memory cards maintain a good marketplace, while in mobile phones and PDAs; the memory card market was at its peak until 2010. After 2010 micro-SD came for new high-end and dominating phones and tablet computers.

Features

In late 2010, Sony and Olympus launched its new products which were only using Memory Stick and XD-Card before respectively are then offered with an additional SD-Card slot. Afterwards that increased the rank of SD-Card's and it was a big step in the favor of SD- Card’s.

Like in computers and other devices video game consoles uses memory cards to hold saved game data. Cartridge-based systems which were primarily using battery-backed RAM within each individual cartridge to hold saves for that particular game level. The Neo Geo AES, released in 1990 by SNK, was the first video game console which was able to use a memory card. AES memory cards were also compatible with Neo-Geo MVS arcade cabinets, allowing players to take their saved game levels from home system to arcade systems and vice versa.

Tips and comments

Memory cards became necessary when home consoles moved to read-only optical discs for storing the game program, beginning with systems such as the Turbo Grafx-CD and Mega-CD. Until the introduction of the sixth generation of video game consoles, memory cards were based on proprietary formats; later systems started using established industry hardware formats for memory cards.
