HIGH IMPEDANCE

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.
