HYI18T256400B - 256-Mbit Double-Data-Rate-Two SDRAM

Download the HYI18T256400B datasheet PDF. This datasheet also covers the HYI18T256160B variant, as both devices belong to the same 256-mbit double-data-rate-two sdram family and are provided as variant models within a single manufacturer datasheet.

Description

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).

Features
