HYI18T256800B 256-Mbit Double-Data-Rate-Two SDRAM

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 a single ended DQS or differential DQS-DQS pair in a source synchrono.
