HYI18T256400B - 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
