Abstract
One embodiment provides a semiconductor device including a plurality of multi-bit memory cells, a first temperature budget sensor, and a circuit. Each of the plurality of multi-bit memory cells is programmable into each of more than two states. The circuit compares a first signal from the first temperature budget sensor to a first reference signal to obtain a first comparison result. The circuit refreshes the plurality of multi-bit memory cells based on the first comparison result.
