GENERAL DESCRIPTION
The M52D128168A is 134,217,728 bits synchronous high data rate Dynamic RAM organized as 4 x 2,097,152 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 lengths and programmable latencies allow the same
device to be useful for a variety of high bandwidth, high performance memory system applications.
