The EM68C16C is a high-speed CMOS Double-Data-Rate-Two (DDR2), synchronous dynamic random-access memory(SDRAM) containing 1024 Mbits in a 16-bit wide data l/Os. It is intermally configured as a 8-bank DRAM,8 banks x 8Mb addresses x 16 l/Os. Thedevice is designed to comply with DDR2 DRAM key features such as posted CAS# with additive latency, Write latency=Read latency -1, Off-Chip Driver(OCD)impedance adjustment, and On Die Termination(ODT).
All of the control and address inputs are synchronized with a pair of extermally supplied differential clocks.
Inputs are latched at the cross point of differential clocks(CK rising and CK# falling). All I/Os are synchronized with a pair of bidirectional strobes(DQS and DQS#) ina source synchronous fashion.

The address bus is used to convey row, column, and bank address information in RAS #, CAS# multiplexing style. Accesses begin withthe registration of a Bank Activate command, and then it is followed by a Read or Write command. Read and write accesses to the DDR2 SDRAM are 4 or 8-bit burst oriented; accesses start at a selected location andcontinue for a programmed number of locations in a programmed sequence. Operating the eight memory banks in an interleaved fashion allows random access operation to occur at a higher rate than is possible with standard DRAMs. An auto precharge function may be enabled to provide a self-timed row precharge that is initiated at the end of the burst sequence.A sequential and gapless data rate is possible depending on burst length, CAS latency, and speed grade of the device.
