:
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.
Command writes can be performed in memory read mode, just as in the command wait state.
Once memory read mode has been entered, consecutive reads can be performed.
After power-on, memory read mode is entered.

2. In memory read mode, the number of cycles depends on the number of address write cycles (n).
