72-Mbit DDRII+ SRAM 2-word Burst

The R1Q#A7236 is a 2, 097, 152-word by 36-bit and the R1Q#A7218 is a 4, 194, 304-word by 18-bit synchronous double data rate static RAM fabricated with advanced CMOS technology using full CMOS sixtransistor memory cell. It integrates unique synchronous peripheral circuitry and a burst counter. All i • Features\n• Power Supply · 1.8 V for core (VDD), 1.4 V to VDD for I/O (VDDQ)\n• Clock · Fast clock cycle time for high bandwidth · Two input clocks (K and /K) for precise DDR timing at clock rising edges only · Two output echo clocks (CQ and /CQ) simplify data capture in high-speed systems · Clock;
