AS4C256M16D3LC-12BCN

AS4C256M16D3LC-12BCN is a 256M x 16-bit DDR3L synchronous DRAM (SDRAM). The 4Gb double-data-rate-3 (DDR3L) DRAM is a double data rate architecture to achieve high-speed operation. It is internally configured as an eight-bank DRAM. The 4Gb chip is organized as 32Mbit x 16 I/Os x8 bank devices. This synchronous device achieves high-speed double-data-rate transfer rates of up to 1866Mb/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 pairs in a source-synchronous fashion.
