      Functional Description
      The CY7C107B and CY7C1007B are high-performance
      CMOS static RAMs organized as 1,048,576 words by 1 bit.
      Easy memory expansion is provided by an active LOW Chip
      Enable (CE) and three-state drivers. These devices have an
      automatic power-down feature that reduces power consump-
      tion by more than 65% when deselected.
      Writing to the devices is accomplished by taking Chip Enable
      (CE) and Write Enable (WE) inputs LOW. Data on the input pin
      (D
      IN
      ) is written into the memory location specified on the ad-
      dress pins (A
      0
      through A
      19
      ).
      Reading from the devices is accomplished by taking Chip En-
      able (CE) LOW while Write Enable (WE) remains HIGH. Under
      these conditions, the contents of the memory location speci-
      fied by the address pins will appear on the data output (D
      OUT
      )
      pin.
      The output pin (D
      OUT
      ) is placed in a high-impedance state
      when the device is deselected (CE HIGH) or during a write
      operation (CE and WE LOW).
      The CY7C107B is available in a standard 400-mil-wide SOJ;
      the CY7C1007B is available in a standard 300-mil-wide SOJ.
