WRITE Mode

The M48T129Y/V is in the WRITE Mode whenever

W (WRITE Enable) and E (Chip Enable) are low

state after the address inputs are stable.

The start of a WRITE is referenced from the latter

occurring falling edge of W or E. A WRITE is termi-

nated by the earlier rising edge of W or E. The ad-

dresses must be held valid throughout the cycle. E

or W must return high for a minimum of tEHAX from

Chip Enable or tWHAX from WRITE Enable prior to

the initiation of another READ or WRITE cycle.

Data-in must be valid tDVWH prior to the end of

WRITE and remain valid for tWHDX afterward. G

should be kept high during WRITE cycles to avoid

bus contention; although, if the output bus has

been activated by a low on E and G a low on W will

disable the outputs tWLQZ after W falls.
