15.6 Auto Page Rewrite Flowchart

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.
