35. Program Cycle Waveforms

36. Sector, Plane or Chip Erase Cycle Waveforms

Notes:

1. Any address can be used to load data.

2. OE must be high only when WE and CE are both low.

3. The data can be 40H or 10H.

4. For chip erase, any address can be used. For plane erase or sector erase, the address depends on what plane or sector is

to be erased.

5. For chip erase, the data should be 21H, for plane erase, the data should be 22H, and for sector erase, the data should

be 20H.
