IS61QDB22M36A 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.
IS61QDB22M36A Key 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
