SanDisk have introduced the 256 megabyte SD Card, a removable, postage
stamp-sized flash memory card. The announcement, made at the Consumer
Electronics Show, doubles the capacity of SanDisk's highest capacity SD Cards
The SD Card is a flash memory storage device with built-in security functions
designed to facilitate the secure exchange of content between devices and the
card. It is 32mm long, 24mm wide and 2.1mm thick. More than 100 products with
slots for the card have been introduced.
The 256MB SanDisk SD Card uses a 1-gigabit (1Gbit, or 1024Megabit) NAND flash
memory chip, the next generation of flash memory that effectively doubles the
amount of storage capacity in these flash memory cards. It is based on the
patented multi-level cell (MLC) technology pioneered by SanDisk that allows two
bits of data to be stored in one memory cell, doubling memory capacity. The
commercialization of NAND MLC flash is a critical step to expand existing
markets and enable new markets for flash memory data storage.
