Abstract
Provided are an apparatus, memory device, and method for using variable voltages to discharge electrons from a memory array during verify recovery operations. In response to verifying voltages in memory cells of the non-volatile memory array programmed during a programming pulse applying charges to the storage cells, a memory controller concurrently applies voltages on wordlines of the non-volatile memory array to clear the non-volatile memory array of electrons and applies voltages to the bitlines to perform bitline stabilization.
