Memory cards are used to store data in devices such as digital video cameras, digital camcorders, mobile phones, media players, etc. They usually contain flash memory and EEPROM have been developed specifically for portable devices where high demands on the smallest size and strength. Otherwise, the memory cards are also resistant to magnetic and electrical fields.
The history of memory cards goes back to the nineties when he began developing a memory card into the PCMCIA slot of notebook computers. Over time, the producers tried to increase the capacity of the equipment, but also reduce its size. At that time, however, prevent the establishment of a single standard, and therefore we now have memory cards that are their characteristics and capacity (from 1GB to 64GB) are very similar, though they have different signs and different formats.
