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

3.
This type of algorithm is used for applications in which the entire array is programmed sequentially, filling the array page-by-
page.
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.
The algorithm above shows the programming of a single page. The algorithm will be repeated sequentially for each page
within the entire array.
