Program Status After Program (SR3)
If excessive data are written (phenomenon whereby the memory cell becomes depressed which results in
data not being read correctly), the block status after-program is set to "1" at the end of the page write
operation. In other words, when writing ends successfully, "8016" is output; when writing fails, "9016" is
output; and when excessive data are written, "8816" is output.
If "1" is written for any of SR5-, SR4- or SR3 bits, the page program-, block erase-, erase all unlocked
blocks- and lock bit program commands are not accepted. Before executing these commands, ex-
ecute the clear status register command (5016) and clear the status register.
Also in the following cases, both SR4 and SR5 are set to "1" (command sequence error).
(1) If data other than "D016" or "FF16" are input for the second bus cycle data of the lock bit
program command (7716/D016).
(2) If data other than "D016" or "FF16" are input for the second bus cycle data of the block erase
command (2016/D016).
(3) If data other than "D016" or "FF16" are input for the second bus cycle data of the erase all
unlocked blocks command (A716/D016). However, inputting "FF16" engages the read array
mode and cancels the setup command in the first bus cycle.
