Note:
Stresses greater than those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this
specification is not implied. Exposure to the absolute maximumratings conditions for extended periodsof time may affect reliability.
CAUTION:
Negatve undershootsbelow –0.3 volts are notallowed on any pin while in the Battery Back-up mode.

also fitsinto many EPROMandEEPROMsockets,
providing the nonvolatility of PROMs without any
requirement for special write timing or limitations
on the number of writes that can be performed.

READ MODE
The M48Z30/30Y is in the Read Mode whenever
W(Write Enable)ishighandE(ChipEnable)islow.
The device architecture allows ripple-through ac-
