GENERAL DESCRIPTION
The M12L16161A is 16,777,216 bits synchronous high data
rate Dynamic RAM organized as 2 x 524,288 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 clock
cycle. 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.
