HYI18T1G400B - 1-Gbit Double-Data-Rate-Two SDRAM
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 synchronous fashion.
A 17-bit address bus for ×4 and ×8 organised components and a 16 bit address bus for ×16 components is used to
