AS4C256M8D3LB-12BIN,AS4C256M8D3LB-12BCN 256M x 8 bit DDR3L Synchronous DRAM (SDRAM)
●Overview
■The 2Gb Double-Data-Rate-3 DRAMs is double data rate architecture to achieve high-speed operation. It is internally configured as an eight bank DRAM.
■The 2Gb chip is organized as 32Mbit x 8 I/Os x 8 bank devices. These synchronous devices achieve high speed double-data-rate transfer rates of up to 1600 Mb/sec/pin for general applications.
■The chip is designed to comply with all key DDR3L 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.
■These devices operate with a single 1.35V -0.067V/ +0.1V power supply and are available in BGA packages.
