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.
