Abstract:
A method and apparatus for modifying a reference voltage between refreshes in a memory device are disclosed. The memory array may include a plurality of memory cells. The memory device may also include a sense amplifier. The sense amplifier may be configured to read data from the plurality of memory cells using a reference voltage. The memory device may also include a sense amplifier reference voltage modification circuit. The sense amplifier reference voltage modification circuit may be configured to detect a triggering event and modify the reference voltage in response to detecting a triggering event.
