Truth Table I – Read/Write Control
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
inTruth Table I.
Timing Waveform of Write Cycle No. 2, CE Controlled Timing
(1,4)
NOTES:
1. R/W or CE must be HIGH during all address transitions.
2. A write occurs during the overlap (t
EW or tWP) of a CE =VIL and R/W = VIL.
3. t
WR is measured from the earlier of CE or R/W going HIGH to the end-of-write cycle.
4. If the CE LOW transition occurs simultaneously with or after the R/W LOW transition, the outputs remain in the High-impedance state.
5. Timing depends on which enable signal (CE or R/W) is asserted last.
NOTE:
1. A
0L - A11L ≠ A0R - A11R
"H" = VIH, "L" = VIL, "X" = Don’t Care, and "Z" = High Impedance
