TEMPERATURE COMPENSATION REFERENCE FOR A TRANSLATION CORRECTION IN A FLASH SPECIAL

摘要

A reference circuit for overerase correction in a flash memory includes a reference flash memory cell biased in a substantially similar manner to that of an overerased flash memory cell. The leakage current for the reference flash memory cell is preset to a tolerable level of leakage current for a maximum operating temperature of the flash memory and the reference flash memory cell tracks the temperature characteristics of the overerased flash memory cell, to avoid costly overcorrection at high temperatures.
