MULTI-BIT MEMORY CELL, AND SEMICONDUCTOR DEVICE WITH TEMPERATURE BUDGET SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a plurality of multi-bit memory cell, a semiconductor device with a first temperature budget sensor, and a method for monitoring the temperature budget of the semiconductor device.;SOLUTION: Each of a plurality of multi-bit memory cells can be programmed to represent three or more states. A circuit compares a first signal received from the first temperature budget sensor with a first reference signal, acquires first comparison results, and refreshes a plurality of multi-bit memory cells based on the first comparison results.;COPYRIGHT: (C)2008,JPO&INPIT
