AT45D08114Algorithm for Programming or Reprogramming of the Entire Array Sequentially START MAIN MEMORY PAGE PROGRAM (82H, 85H)END provide address and data BUFFER WRITE (84H, 87H)BUFFER to MAIN MEMORY PAGE PROGRAM (83H, 86H)Figure 1Notes: 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.元器件交易网
