GENERAL DESCRIPTION
The M12S64164A is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x 1,048,576 words by
16 bits. Synchronous design allows precise cycle controls 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.
