Abstract:
A non-volatile memory apparatus and a refresh method thereof are provided. A control circuit determines whether threshold voltages of memory cells in a memory sectors are larger than a refresh read reference voltage and smaller than a refresh program verify reference voltage, and the control circuit determines that a memory cell needs refreshing if the threshold voltage of the memory cell is larger than the refresh read reference voltage and smaller than the refresh program verify reference voltage.

Claim (Index 5):
The non-volatile memory apparatus of  claim 1 , wherein the control circuit comprises a plurality of sense circuits, each of the sense circuits comprising:\n a first sense amplifier having a positive end and a negative end receiving a sensed voltage corresponding to stored data of a target sensed memory cell and a first reference voltage respectively; a second sense amplifier having a positive end and a negative end receiving the corresponding sensed voltage and a second reference voltage; and a refresh enable circuit, coupled to the first sense amplifier and the second sense amplifier and outputting a refresh enable signal which enables the control circuit to refresh the target sensed memory cell according to a comparison result of the first sense amplifier and the second sense amplifier.
