For the P-Flash banks, a programmed wordline (WL) must be erased before it can be
reprogrammed as the Flash cells can only withstand one gate disturb. This means that
the entire sector containing the WL must be erased since it is impossible to erase a
single WL.
For the D-Flash bank, the same WL can be programmed twice before erasing is required
as the Flash cells are able to withstand two gate disturbs. Hence, it is possible to
program the same WL, for example, with 16 bytes of data in two times (see
Figure 12
).

D-Flash Programming
Note: When programming a D-Flash WL the second time, the previously programmed
Flash memory cells (whether 0s or 1s) should be reprogrammed with 0s to retain
its original contents and to prevent “over-programming”.
