DESCRIPTION
The M66255FP is a high-speed line memory with a FIFO
(First In First Out) structure of 8192-word
×
10-bit configura-
tion which uses high-performance silicon gate CMOS pro-
cess 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.
FEATURES
