Notes: 1. In auto-program mode, 129 cycles are required for command writing by means of a
simultaneous 128-byte write.
2. In memory read mode, the number of cycles depends on the number of address write
cycles (n).
6.8.4
Memory Read Mode
1. After the end of an auto-program, auto-erase, or status read operation, the command wait state
is entered. To read memory contents, a transition must be made to memory read mode by
means of a command write before the read is executed.
2. Command writes can be performed in memory read mode, just as in the command wait state.
3. Once memory read mode has been entered, consecutive reads can be performed.
4. After power-on, memory read mode is entered.
5. Do not make a setting outside the valid address range.
