28. Auto Page Rewrite Flowchart
Figure 50. Algorithm for Programming or Re-programming of the Entire Array Sequentially
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 is repeated sequentially for each
page within the entire array.
