FEATURES

GENERAL DESCRIPTION

The M52L32321A 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, high

performance memory system applications.

3.3V power supply

LVCMOS compatible with multiplexed address

Dual banks operation

MRS cycle with address key programs

CAS Latency (1, 2 & 3 )

Burst Length (1, 2, 4, 8 & full page)

Burst Type (Sequential & Interleave)

EMRS cycle with address key programs.

All inputs are sampled at the positive going edge of the

system clock

Burst Read Single-bit Write operation

Special Function Support.
