Figure 1. Algorithm for Programming or Reprogramming of an Entire Sector Sequentially
Notes:
1.
2.
3.
This type of algorithm is used for applications in which an entire sector is programmed sequentially, filling the sector 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 sector.
