A voltage raising circuit of a semiconductor memory includes a compensating circuit. The compensating circuit has a negative dependency on a source voltage for controlling a variation of a raised voltage caused by a variation of the source voltage, and a positive dependency on temperature for controlling a variation of the raised voltage caused by a variation of the temperature.
