DESCRIPTION
The M66256FP is a high-speed line memory with a FIFO
(First In First Out) structure of 5120-word
×
8-bit configuration
which uses high-performance silicon gate CMOS process
technology.
It has separate clock, enable and reset signals for write and
read, and is most suitable as a buffer memory between de-
vices with different data processing throughput.
