GENERAL DESCRIPTION
The M32L1632512A is 16, 777, 216 bits synchro-
nous high data rate Dynamic RAM organized as 2 x
262, 144 words by 32 bits, fabricated with ESMT’s
high performance CMOS technology. Synchronous
design allows precise cycle control with the use of
system clock. I/O transactions are possible on every
clock cycle. Range of operating frequencies , progra-
mmable burst length, and programmable latencies
allows the same device to be useful for a variety of
high bandwidth, high performance memory system
applications.
Write per bit and 8 columns block write improves
performance in graphic systems.
