M48Z512A, M48Z512AY
WRITE MODE
The M48Z512A/512AY is in the Write Mode when-
ever W and E are active. The start of a write is ref-
erenced from thelatter occurringfalling edge of W
or E.Awriteis terminatedby the earlier rising edge
of W or E.
The addresses must be held valid throughout the
cycle. Eor W must return high for a minimum of t
E-

CC
= 4.75V to 5.5V or 4.5V to 5.5V)
Note: 1. C
= 5pF.
2. If E goes low simultaneously with W going low, the outputs remain in the high impedance state.
