Abstract
Embodiments disclosed herein are directed to performing a single-side gate-induced drain leakage (GIDL) erase operation. Control circuitry may be configured to perform a single-side GIDL erase operation on a memory block in which a selected sub-block is erased while an unselected sub-block is not erased. During the single-side GIDL erase operation, the control circuitry may be configured to apply a first unselect bias voltage to a first set of word lines of the unselected sub-block, where the first set of word lines is associated with a first word line zone and the first word line zone is associated with an unselect bias voltage, and apply a second unselect bias voltage to a second set of word lines of the unselected sub-block, where the second set of word lines is associated with a second word line zone and the second word line zone is associated with another unselect bias voltage.
