GENERAL DESCRIPTION
The M12L32321A is 33,554,432 bits synchronous high data rate Dynamic RAM organized as 2 x 524,288 words by 32 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, h.
