Figure 18.
The device status can be read out by inputting the Status Read command “70h” in Read mode.
Once the device has been set to Status Read mode by a “70h” command, the device will not return to
Read mode.
Therefore, a Status Read during a Read operation is prohibited.
However, when the Read command “00h” is input during [A], Status mode is reset and the device returns
to Read mode. In this case, data output starts automatically from address N and address input is
unnecessary

If the programming result for page address M is Fail, do not try to program the
page to address N in another block without the data input sequence.
Because the previous input data has been lost, the same input sequence of 80h
command, address and data is necessary.

(9) RY/BY : termination for the Ready/Busy pin ( RY/BY )
A pull-up resistor needs to be used for termination because the RY / BY buffer consists of an open drain
circuit.
