WRITE mode
The M48Z512A/Y/V is in the WRITE mode whenever W and E are active. The start of a
WRITE is referenced from the latter occurring falling edge of W or E. A WRITE is terminated
by the earlier rising edge of W or E.
The addresses must be held valid throughout the cycle. E or W must return high for a
minimum of t
cycle. Data-in must be valid t

contention; although, if the output bus has been activated by a low on E and G, a low on W
will disable the outputs t
