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.

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.
