General Description

The R1Q6A7236 is a 2,097,152-word by 36-bit and the R1Q6A7218 is a 4,194,304-word by 18-bit synchronous double data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.

It integrates unique synchronous peripheral circuitry and a burst counter.

All input registers are controlled by an input clock pair (K and /K) and are latched on the positive edge of K and /K.

Overview

Key Features

  • ႑ Power Supply.
  • 1.8 V for core (VDD), 1.4 V to VDD for I/O (VDDQ) ႑ Clock.
  • Fast clock cycle time for high bandwidth.
  • Two input clocks (K and /K) for precise DDR timing at clock rising edges only.
  • Two input clocks for output data (C and /C) to minimize clock skew and flight time mismatches.
  • Two output echo clocks (CQ and /CQ) simplify data capture in high-speed systems.
  • Clock-stop capability with μs restart ႑ I/O.
  • Separate independent.
