DQ13, DQ12, DQ11 = “000”
0 programmed, 2 total
Note:
Figure assumes address DQ0 is not at an address boundary, active clock edge is rising, and wait state is set to
“101”.
Figure 30. Example of Wait States Insertion
Note:
Breakpoints in waveforms indicate that system may alternately read array data from the “non-busy bank” while
checking the status of the program or erase operation in the “busy” bank. The system should read status twice to ensure
valid information.
