AS4C256M16D3LB-12BAN - 4Gb DRAM

Description

Clock : CK and CK are differential clock inputs.

All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK.

Features

• - Double-data-rate architecture; two data transfers per clock cycle - The high-speed data transfer is realized by the 8 bits prefetch pipelined architecture - Bi-directional differential data strobe (DQS and DQS) is transmitted/received with data for capturing data at the receiver - DQS is edge-aligned with data for READs; center-aligned with data for WRITEs - Differential clock inputs (CK and CK) - DLL aligns DQ and DQS transitions with CK transitions - Commands entered on each positive CK edge.
