● Full Status Check
By performing full status check, it is possible to know the execu-
tion results of erase and program operations. Figure 101 shows a
full status check flowchart and the action to be taken when each
error occurs.
Fig. 101 Full status check flowchart and remedial procedure for errors
Read status register
SR4 = “1” and
SR5 = “1” ?
NO
YES
SR5 = “0” ?
YES
Erase error
NO
SR4 = “0” ?
YES
NO
Command
sequence error
Program error
End (block erase, program)
Execute the clear status register command (5016)
to clear the status register. Try performing the
operation one more time after confirming that the
command is entered correctly.
Should an erase error occur, the block in error
cannot be used.
Note: When one of SR5 and SR4 is set to “1”, none of the read array, program,
and block erase commands is accepted. Execute the clear status register
command (5016) before executing these commands.
Should a program error occur, the block in error
cannot be used.
