1. 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 sections of this

specification is not implied.

Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

NOTE:

1. Pins 3,4,6,and 7 (PD0-3) are read by the user to determine the density of

the module. If PD0, PD1 read GND and PD2, PD3 read OPEN, then the

module has a 256K depth.
