Functional Description
The CY7C1146V18, CY7C1157V18, CY7C1148V18, and CY7C1150V18 are 1.8V Synchronous Pipelined SRAMs equipped with DDR-II+ architecture. The DDR-II+ consists of an SRAM core with advanced synchronous peripheral circuitry. Addresses for read and write are latched on alternate rising edges of the input (K) clock. Write data is registered on the rising edges of both K and K. Read data is driven on the rising edges of K and K. Each address location is associated with two 8-bit words (CY7C1146V18) or 9-bit words (CY7C1157V18) or 18-bit words (CY7C1148V18) or 36-bit words (CY7C1150V18) that burst sequentially into or out of the device. Asynchronous inputs include output impedance matching input (ZQ). Synchronous data outputs (Q, sharing the same physical pins as the data inputs D) are tightly matched to the two output echo clocks CQ/CQ, eliminating the need for separately capturing data from each individual DDR SRAM in the system design.
