Figure 25-1. Algorithm for Programming or Re-programming 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
