SYSTEM FOR IMPROVING ENDURANCE AND DATA RETENTION IN MEMORY DEVICES

摘要

A memory system includes a memory block having at least one memory cell. The current is sensed after the erase operations of the memory cell. A signal is generated in response to the current dropping below a predetermined level after the erase operations of the memory cell. The stress on the memory cell is reduced to a first reduced level for erase operations occurring subsequent to the current dropping below the predetermined level.
