Timing Waveform of Write with Port-to-Port Read(1, 2)
.unctional Description
The IDT7054 provides four ports with separate control, address, and
I/Opinsthatpermitindependentaccessforreadsorwritestoanylocation
in memory. These devices have an automatic power down feature
controlled by
CE. The CE controls on-chip power down circuitry
thatpermitstherespectiveporttogointostandbymodewhennotselected
(
CE = VIH). When a port is enabled, access to the entire memory array
ispermitted.EachporthasitsownOutputEnablecontrol(
OE).Intheread
mode, the port’s
OE turns on the output drivers when set LOW. READ/
WRITE conditions are illustrated in the table.
Table I Read/Write Control
NOTES:
1. "H" = VIH, "L" = VIL, "X" = Don’t Care, "Z "= High Impedance
2. For valid write operation, no more than one port can write to the same address
location at the same time.

OE = VIL for the reading ports.
2. All timing is the same for left and right ports. Port "A" may be either of the four ports and Port "B" is any other port.
