ABSTRACT:
A negative voltage generator of a semiconductor memory device includes: a flag signal generation unit for receiving a temperature information code from an On Die Thermal Sensor (ODTS) to output a plurality of flag signals containing temperature information of the semiconductor memory device; and a negative voltage detection unit for detecting a negative voltage to output a detection signal for determining whether to pump a negative voltage, wherein a detection level of the negative voltage is changed according to the flag signals.
