GENERAL DESCRIPTION
This EMD28164PA is 134,217,728 bits synchronous double data rate Dynamic RAM. Each 33,554,432 bits bank is organized as 4,096 rows by 512 columns by 16 bits, fabricated with EMLSI’s high performance CMOS technology.
This device uses a double data rate architecture to achieve highspeed 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.
