AS4C64M16D3B-12BCN

AS4C64M16D3B-12BCN is a 64M x 16bit DDR3 synchronous DRAM (SDRAM). The 1Gb double-data-rate-3 DRAM is double data rate architecture to achieve high-speed operation. It is internally configured as an eight bank DRAM. The 1Gb chip is organized as 8Mbit x 16 I/Os x 8 bank devices. This synchronous device achieves high speed double-data-rate transfer rates of up to 1600Mb/sec/pin for general applications. The chip is designed to comply with all key DDR3 DRAM key features and 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 CK# falling). All I/Os are synchronized with differential DQS pair in a source synchronous fashion.
