IS61DDB21M18A Overview
The 18Mb IS61DDB251236A and IS61DDB21M18A are synchronous, high-performance CMOS static random access memory (SRAM) devices. These SRAMs have a mon I/O bus. The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed.
IS61DDB21M18A Key Features
- 512Kx36 and 1Mx18 configuration available
- On-chip delay-locked loop (DLL) for wide data valid
- mon I/O read and write ports
- Synchronous pipeline read with self-timed late write
- Double Data Rate (DDR) interface for read and
- Fixed 2-bit burst for read and write operations
- Clock stop support
- Two input clocks (K and K#) for address and control
- Two input clocks (C and C#) for data output control
- Two echo clocks (CQ and CQ#) that are delivered
