take place in a maximum time of t
EP
. During this time, the status register will indicate that the
part is busy.
If a sector is programmed or reprogrammed sequentially page-by-page, then the programming
algorithm shown in
Figure 17-1
on
page 27
is recommended. Otherwise, if multiple bytes in a
page or several pages are programmed randomly in a sector, then the programming algorithm
shown in
Figure 17-2
on
page 28
is recommended. Each page within a sector must be
updated/rewritten at least once within every 10,000 cumulative page erase/program operations
in that sector.

Operation Mode Summary
The modes described can be separated into two groups – modes which make use of the Flash
memory array (Group A) and modes which do not make use of the Flash memory array (Group
B).
Group A modes consist of:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Main Memory Page Read
Main Memory Page to Buffer 1 (or 2) Transfer
Main Memory Page to Buffer 1 (or 2) Compare
Buffer 1 (or 2) to Main Memory Page Program with Built-in Erase
Buffer 1 (or 2) to Main Memory Page Program without Built-in Erase
Page Erase
Block Erase
Main Memory Page Program through Buffer
Auto Page Rewrite
Group B modes consist of:
1.
2.
3.
Buffer 1 (or 2) Read
Buffer 1 (or 2) Write
Status Register Read
If a Group A mode is in progress (not fully completed) then another mode in Group A should not
be started. However, during this time in which a Group A mode is in progress, modes in Group B
can be started.
This gives the Serial DataFlash the ability to virtually accommodate a continuous data stream.
While data is being programmed into main memory from buffer 1, data can be loaded into buffer
2 (or vice versa). See application note AN-4 (“Using Atmel’s Serial DataFlash”) for more details.
