CE CONTROLLED WRITE CYCLE
Page Write Cycle
Notes: (7) Between successive byte writes within a page write operation, OE can be strobed LOW: e.g. this can be done with CE and WE HIGH
to fetch data from another memory device within the system for the next write; or with WE HIGH and CE LOW effectively performing a
polling operation.
(8) The timings shown above are unique to page write operations. Individual byte load operations within the page write must conform to
either the CE or WE controlled write cycle timing.
