    256K x 4 Bit Fast Static Random
    Access Memory
    The MCM6729D is a 1,048,576 bit static random access memory organized
    as 262,144 words of 4 bits. Static design eliminates the need for external clocks
    or timing strobes.
    Output enable (G) is a special control feature that provides increased system
    flexibility and eliminates bus contention problems.
    This device meets JEDEC standards for functionality and revolutionary pinout,
    and is available in a 400 mil plastic small–outline J–leaded package.
    Single 5 V
    ±
    10% Power Supply
    Fully Static — No Clock or Timing Strobes Necessary
    All Inputs and Outputs Are TTL Compatible
    Three State Outputs
    Fast Access Times: 8, 10, 12 ns
    Center Power and I/O Pins for Reduced Noise
