Programming
A logic one can be permanently programmed into a selected bit location by using
special equipment (programmer). First, the desired word is selected by the ten address
inputs in TTL levels. Either or both of the two chip select inputs must be ata logic
one (high); Secondly, a train of high current programming pulses is applied to the
desired output. After the sensed voltage indicates that the selected bit is in the logic
one state, an additional pulse train is applied, then is stopped.
Reading
To read the memory, both of the two chip select inputs should be held at logiC zero
(low). The outputs then correspond to the data programmed in the selected words.
When either or both of the two chip select inputs are at logic one (high). all the
....-----,outputs will be high (floating) .

ABSOLUTE MAXIMUM
RATINGS*
COMMENT: Stress above those listed under "Absolute Maximum Ratings" may cause permanellt
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 device
reliability.
