Figure 1. Algorithm for Sequentially Programming or Reprogramming the Entire Array

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.
