GENERAL DESCRIPTION
The M12L128324A is 134,217,728 bits synchronous high data rate Dynamic RAM organized as 4 x 1,048,576 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.
