Figure 4b. Write Cycle 2: R/W Three-States Data I/Os (Either Port)
Assumptions:
1.
The internal write time of memory is defined by the overlap of CE
LOW and R/W LOW. Both signals must be LOW to initialize a write,
and either signal can terminate a write by going HIGH. The data input
set-up and hold timing should be referenced to the rising edge of the sig-
nal that terminates the write.
2. R/W must be HIGH during all address transactions.
3. Data I/O pins enter high impedance even if OE is held LOW during
write.
