A driving voltage driver for sense amplifier of memory device

PURPOSE: A driving voltage driver for a sense amplifier of a memory device is provided to improve the driving capability by having the first and the second core voltage level-up means. CONSTITUTION: A driving voltage driver for a sense amplifier of a memory device comprises a driving voltage driver for generating the steady voltage used as the driving voltage of a sense amplifier to a driving voltage node; the first core voltage level-up means(602) connected with a supply voltage and the driving voltage node; the second core voltage level-up means(603) connected with the supply voltage and the driving voltage node. The first and the second core voltage level-up means are turned on in order so that the voltage level of the driving voltage node connected to the sense amplifier is raised to the level of the supply voltage.
