NT5TU64M16DG-AD 1Gb DDR2 SDRAM

The 1giga-bit (1Gb) Double-Data-Rate-2 (DDR2) DRAMs is a high-speed CMOS Double Data Rate 2 SDRAM containing 1,073,741,824 bits. It is internally configured as an octal-bank DRAM. The 1Gb chip is organized as 32Mbit x 4 I/O x 8 bank, 16Mbit x 8 I/O x 8 bank or 8Mbit x 16 I/O x 8 bank device. These synchronous devices achieve high speed double-data-rate trans.

Features

(1) posted CAS with additive latency, (2) write latency = read latency -1, (3) normal and weak strength data-output driver, (4) variable data-output impedance adjustment and (5) an ODT (On-Die Termination) function. All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CK rising and  falling). All I/Os are synchronized with a single ended DQS or differential DQS pair in a source synchronous fashion. A 14 bit address bus for x4/x8 organized components and A 13 bit address b.
