IS61DDB44M18A Description
The 72Mb IS61DDB42M36A and IS61DDB44M18A 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.
IS61DDB44M18A Key Features
- 2Mx36 and 4Mx18 configuration available
- On-chip delay-locked loop (DLL) for wide data valid
- mon I/O read and write ports
- Synchronous pipeline read with late write operation
- Double Data Rate (DDR) interface for read and
- Fixed 4-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
