Page Mode Read
The device is capable of fast page mode read and is compatible with the page
mode Mask ROM read operation. This mode provides faster read access speed for
random locations within a page. Address bits Amax–A3 select an 8 word page,
and address bits A2–A0 select a specific word within that page. This is an asyn-
chronous operation with the microprocessor supplying the specific word location.
The random or initial page access is t

page) is equivalent to t

should be used to gate data to the output inputs if the device is selected. Fast
page mode accesses are obtained by keeping Amax–A3 constant and changing
A2–A0 to select the specific word within that page.
In addition to the conventional features (read, program, erase-suspend read, and
erase-suspend program), the device is capable of reading data from one bank of
memory while a program or erase operation is in progress in another bank of
memory (simultaneous operation). The bank can be selected by bank addresses
(A21–A19) with zero latency.
The simultaneous operation can execute multi-function mode in the same bank.
