Abstract
A semiconductor memory device capable of measuring a temperature without the influence of noise includes a temperature sensing device for sensing a current temperature in response to a control signal, wherein the semiconductor memory device enters a power save mode for a predetermined time starting from an activation of the control signal and wherein the power save mode has substantially no power consumption. A method for driving a semiconductor memory device in accordance with the present invention includes sensing a current temperature in response to a control signal and entering a power save mode for a predetermined time starting from an activation of the control signal, wherein the power save mode has substantially no power consumption.
