Figure 25-1. Algorithm for Programming or Reprogramming of the Entire Array Sequentially
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
