ESMMC256 / ESMMC512 are 64MB
up to 512MB MultiMediaCardTM. These
are the highly integrated flash memory
with serial and random accessible via a
dedicated serial interface optimized for fast
and reliable data transmission. They are
fully compatible to a new consumer
standard, called the MultiMediaCardTM
system standard defined in the
MultiMediaCardTM system specification.
The MultiMediaCardTM system is a new
mass-storage system based on innovations
in semiconductor technology. It has been
designed to provide an inexpensive,
mechanically robust storage medium in
card form for multimedia consumer
applications and mobile devices (handheld
PCs, digital cameras, MP3 players, etc.) to
store, copy, and move information like a
small hard drive.
