GENERAL DESCRIPTION

This EMD12324P is 536,870,912 bits synchronous double data

rate Dynamic RAM. Each 134,217,728 bits bank is organized as

8,192 rows by 512columns by 32 bits, fabricated with EMLSI’s

high performance CMOS technology.

This device uses a double data rate architecture to achieve high-

speed operation. The double data rate architecture is essentially

a 2n-prefetch architecture with an interface designed to transfer

two data words per clock cycle at the I/O balls.

Range of operating frequencies, programmable burst lengths

and programmable latencies allow the same device to be useful

for a variety of high bandwidth and high performance memory

system applications.
