Key Features

  • a 2 line control function which accommodates the use of multiple memory connection. The two line control function allows:.
  • the lowest possible memory power dissipation,.
  • complete assurance that output bus contention will not occur. For the most efficient use of these two control lines, E should be decoded and used as the primary device selecting function, while G should be made a common connection to all devices in the array and connected to the READ line from the system control bus.
