GRNERAL DESCRIPTION
The T436416A is 67,108,864 bits synchronous
high data rate Dynamic RAM organized as
4 x 1,048,576 words by 16 bits , fabricated with
high performance CMOS technology .
Synchronous design allows precise cycle control
with the use of system clock I/O transactions are
possible on every clockcycle . Range of operating
frequencies , programmable burst length and
programmable latencies allow the same device to
be useful for a variety of high bandwidth , high
performance memory system applications.
