IS61QDB42M36 - QUAD (Burst of 4) Synchronous SRAMs

The 72Mb IS61QDB42M36 and IS61QDB44M18 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.

• 2M x 36 or 4M x 18.
• On-chip delay-locked loop (DLL) for wide data valid window.
• Separate read and write ports with concurrent read and write operations.
• Synchronous pipeline read with late write operation.
• Double data rate (DDR) interface for read and write input ports.
• Fixed 4-bit burst for read and write operations.
• Clock stop support.
• Two input clocks (K and K) for address and control registering at rising edges o.
