The same WL can be programmed twice before erasing is required as the Flash cells
are able to withstand two gate disturbs. This means if the number of data bytes that
needs to be written is smaller than the 32-byte minimum programming width, the user
can opt to program this number of data bytes (x; where x can be any integer from 1 to
31) first and program the remaining bytes (32 - x) later. Hence, it is possible to program
the same WL, for example, with 16 bytes of data in two times (see
Figure 11
Note: When programming a 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”.
