FUNCTIONAL DESCRIPTION
The IDT7134 provides two ports with separate control,
address, and I/O pins that permit independent access for
reads or writes to any location in memory. These devices have
an automatic power down feature controlled by
CE
. The
CE
controls on-chip power down circuitry that permits the
respective port to go into standby mode when not selected
(
CE
high). When a port is enabled, access to the entire
memory array is permitted. Each port has its own Output
Enable control (
OE
). In the read mode, the port’s
OE
turns on
the output drivers when set LOW. Non-contention READ/
WRITE conditions are illustrated in the table below.
