Overview
The EM68916D is 134,217,728 bits of double data
rate synchronous DRAM organized as 4 banks of
2,097,152 words by 16 bits. The synchronous
operation with Data Strobe allows extremely high
performance. EM68916D is applied to reduce
leakage and refresh currents while achieving very
high speed. I/O transactions are possible on both
edges of the clock. The ranges of operating
frequencies, programmable burst length and
programmable latencies allow the device to be
useful for a variety of high performance memory
system applications.
