GENERAL DESCRIPTION

The M12L64322A is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x 524,288 words by 32 bits.

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.
