GENERAL DESCRIPTION
16MB and 32MB solid-state memories organized in a x36
configuration. During READ or WRITE cycles, each bit is
uniquely addressed through the 22 address bits, which are
entered 11 bits (A0 -A10) at a time. RAS# is used to latch the
first 11 bits and CAS# the latter 11 bits. A READ or WRITE

cycle is selected with the WE# input. A logic HIGH on WE#
dictates READ mode, while a logic LOW on WE# dictates
WRITE mode. During a WRITE cycle, data-in (D) is latched
by the falling edge of CAS#. Since WE# goes LOW prior to
CAS# going LOW, the output pin(s) remain open (High-Z)
until the next CAS# cycle.
