A3R56E40ABF Features

* Double-data-rate architecture; two data transfers per clock cycle

* The high-speed data transfer is realized by the 4 bits prefetch pipelined architecture

* Bi-directional differential data strobe (DQS and /DQS) is transmitted/received with data for capturing data at the re
