IS61QDB22M36A Features

2Mx36 and 4Mx18 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.
Fixed 2-bit burst for read and write operations.
Clock stop support.
Two input clocks (K and K#) for address and control registering at rising edges only. Two output clocks (C and C#) for data output control. Two echo clocks (CQ and CQ#) that are delivered simultaneously with data. +1.8V core power supply and 1.5, 1.8V VDDQ, used with 0.75, 0.9V VREF.

Overview

The 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.
