BUFFER TO MAIN
MEMORY PAGE PROGRAM
(83H, 86H)

Notes:
1. This type of algorithm is used for applications in which the entire array is programmed sequentially, filling the array page-by-
page.
2. A page can be written using either a Main Memory Page Program operation or a Buffer Write operation followed by a Buffer
to Main Memory Page Program operation.
3. The algorithm above shows the programming of a single page. The algorithm will be repeated sequentially for each page
within the entire array.
