      DESCRIPTION
      The
      ISSI
      IS61C256AH is a very high-speed, low power,
      32,768 word by 8-bit static RAMs. They are fabricated using
      ISSI
      's high-performance CMOS technology. This highly reli-
      able process coupled with innovative circuit design tech-
      niques, yields access times as fast as 10 ns maximum.
      When
      CE
      is HIGH (deselected), the device assumes a standby
      mode at which the power dissipation can be reduced down to
      250
      μ
      W (typical) with CMOS input levels.
      Easy memory expansion is provided by using an active LOW
      Chip Enable (
      CE
      ) input and an active LOW Output Enable (
      OE
      )
      input. The active LOW Write Enable (
      WE
      ) controls both writing
      and reading of the memory.
      The IS61C256AH is pin compatible with other 32K x 8 SRAMs
      and are available in 28-pin PDIP, SOJ, and TSOP (Type I)
      packages.
