    • A power supply device for a temperature sensor is provided to increase a low source voltage margin by boosting an input voltage to be higher than a source voltage by using a pumping power supply unit. A power supply device for a temperature sensor includes a non-pumping power supply unit(10), a pumping power supply unit(30), and a controller. The non-pumping power supply unit includes an MOS(Metal Oxide Semiconductor) switch, whose output terminal is connected to the temperature sensor. The non-pumping power supply unit boosts up a source voltage from the operation starting time of the temperature sensor until an output voltage level of the non-pumping power supply unit reaches a first target voltage level, and outputs the boosted voltage to the temperature sensor. The pumping power supply unit boosts up the source voltage by using a charge pumping process and outputs the boosted voltage. The controller supplies an output from the pumping power supply unit to the temperature sensor, after the output voltage level of the non-pumping power supply unit reaches the first target voltage level.

    • PURPOSE: An array supply voltage generation circuit of a semiconductor memory device and a method for driving a sense amplifier are provided to enhance the data sensing speed and the data reading speed by generating the first supply voltage for sensing and amplifying data and the second supply voltage for storing the data into a memory cell. CONSTITUTION: An array supply voltage generation circuit of a semiconductor memory device includes a first circuit and a second circuit. The first circuit(1) includes a differential amplifier for receiving the first supply voltage, and a PMOS transistor. The PMOS transistor includes a gate connected to an output terminal of the differential amplifier, a source for receiving the second supply voltage, and a drain connected to a capacitor. An array supply voltage is formed as the first supply voltage level by feeding back the array supply voltage of the drain of the PMOS transistor to the differential amplifier. The second circuit(2) is connected to the first circuit in order to form the array supply voltage as the second supply voltage level. A process for sensing data of a bit line and a bit line bar is performed by outputting the second supply voltage level according to an inputting state of a data rear command signal. The data are stored into a memory cell by changing the array supply voltage to the first supply voltage level.
