GENERAL DESCRIPTION

The EMLS232UA series is 67,108,864 bits synchronous high data

rate Dynamic RAM organized as 4 x 534,288 words by 32 bits,

fabricated with Ramsway’s high performance CMOS technology.

Synchronous design allows precise cycle control with the use of

system clock and I/O transactions are possible on every clock

cycle. 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 mem-

ory system applications.
