18-Mbit Burst of 4 Pipelined SRAM with QDR™ Architecture
Features
Functional Description
• Separate independent Read and Write data ports — Supports concurrent transactions
• 167-MHz Clock for high bandwidth — 2.5 ns Clock-to-Valid access time
• 4-Word Burst for reducing the address bus frequency • Double Data Rate (DDR) interfaces on both Read & Write
Ports (data transferred at 333 MHz) @167 MHz • Two input clocks (K and K) for precise DDR timing
— SRAM uses rising edges only • Two input clocks for output data (C and C) to minimize
clock-skew and flight-time mismatches. • Single multiplexed address input bus latches address
inputs for both Read and Write ports • Separate Port Selects for depth expansion • Synchronous internally self-timed writes • 1.
