MMCplus
Features
TS128MMC4 ~ TS4GMMC4 is a 128MB ~ 4GB
MMCplus memory card. It’s a fastest, low-power,
highly integration memory card. It is 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 data at high-speed transfer rate.
