Figure 15-1. Algorithm for Programming or Reprogramming of the Entire Array Sequentially
START
provide address
and data
MAIN MEMORY PAGE PROGRAM
THROUGH BUFFER
(82H, 85H)
BUFFER WRITE
(84H, 87H)
BUFFER TO MAIN
MEMORY PAGE PROGRAM
(83H, 86H)
END
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.
