Abstract
The data read circuit includes a variable current generation circuit and a data sensing circuit. The variable current generation circuit is configured to generate a variable current that varies in response to an external temperature. The data sensing circuit is configured to sense and amplify data on a bit line connected to a non-volatile memory cell according to the variable current and to configured to output the sensed and amplified data. The data sensing circuit controls a margin for sensing the data according to the variable current.
