Abstract:
Control logic in a memory device cause a programming pulse to be applied to a set of wordlines including a first set of even-numbered wordlines corresponding to a first set of memory cells to be erased and a second set of odd-numbered wordlines corresponding to a second set of memory cells to be erased, where a set of electrons are injected into a first set of gate regions, a second set of gate regions, and a set of inter-cell regions of a charge trap (CT) layer of the memory device. The control logic executes a first erase cycle on the first set of even-numbered wordlines to remove a first subset of electrons from the first set of gate regions corresponding to the first set of even-numbered wordlines. The control logic executes a second erase cycle on the second set of odd-numbered wordlines to remove a second subset of electrons from the second set of gate regions corresponding to the second set of even-numbered wordlines.
