IS61QDPB251236A Product details

Description

The and are synchronous, high- performance CMOS static random access memory (SRAM) devices.These SRAMs have separate I/Os, eliminating the need for high-speed bus turnaround.The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed.Refer to the for a description of the basic operations of these SRAMs.Read and write addresses are registered on alternating rising edges of the K clock.Read and write performed in double data rate.The

Features

512Kx36 and 1Mx18 configuration available.
On-chip Delay-Locked Loop (DLL) for wide data valid window.
Separate independent read and write ports with concurrent read and write operations.
Synchronous pipeline read with EARLY write operation.
Double Data Rate (DDR) interface for read and write input ports.
2.5 Cycle read latency.
Fixed 2-bit burst for read and write operations.
Clock stop support.
Two input clocks (K and K#) for address and co.
