Abstract
The invention provides a non-volatile memory apparatus and an erasing method thereof. The non-volatile memory apparatus includes a plurality of memory sectors and a control voltage provider. The memory sectors disposed in a same well, wherein, each of the memory sectors includes a plurality of memory cells for respectively receiving a plurality of control line signals. The control voltage provider provides the control line signals to the memory cells of each of the first memory sectors. When an erasing operation is operated, one of the memory sectors is selected for erasing and the control voltage provider provides the control line signals of the selected memory sector with an erase control voltage and provides the control line signals of the un-selected memory sectors with a un-erase control voltage, voltage levels of the erase control voltage and the un-erase control voltage are different.
