*The RY/BY# is an open drain output pin and indicates status of the internal WSM. When low,it indicates that the WSM is Busy performing an operation.

A pull-up resistor of 10K-100K Ohms is required to allow the RY/BY# signal to transition high indicating a Ready WSM condition.

*DQ3 indicates the block status after the page programming, byte/word programming and page buffer to flash. When DQ3 is "1", the page has the

over-programed cell . If over-program occurs, the device is block fail. However if DQ3 is "1", please try the block erase to the block. The block may revive.
