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.
