Figure 1. Algorithm for Programming or Reprogramming of an Entire Sector Sequentially

Notes:

1.

This type of algorithm is used for applications in which an entire sector is programmed sequentially, filling the sector 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 sector.
