BASIC DESCRIPTION
MultiMedia Cards are extremely small and lightweight flash cards suitable for use in protable multimedia productssush as cellular phones and protable audio players.
A MultiMediaCard consists of flash memory and a controller.
The Leaddata MultiMediaCard is a highly integrated flash memory with serial
and random access capability.
It is accessible via a dadicated serial interface optimized for fast and reliable data transmission.
