(7) Status Read during a Read operation
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
unless the Read command “00h” is inputted during [A]. If the Read command “00h” is inputted during [A],
Status Read 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

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

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.
