Several programming cycles on the same page (Partial Page Program)
Note regarding the RE signal
Therefore, once the device has been set to Read mode by a “00H”, “01H” or “50H” command, the internal
column address counter is incremented by the RE clock independently of the address input timing, If the
internal read operation (array to register) will occur and the device will enter Busy state. (Refer to Figure 25.)
RE clock input pulses start before the address input, and the pointer reaches the last column address, an

nth programming
A page can be divided into up to 3 segments. Each segment can be programmed individually as follows:
Hence the RE clock input must start after the address input.
RE The internal column address counter is incremented synchronously with the RE clock in Read mode.

Result
Note: The input data for unprogrammed or previously programmed page segments must be “1”
(i.e. the inputs for all page bytes outside the segment which is to be programmed should be set to all “1”).
