A voltage boosting circuit having an asymmetric MOS in DRAM. A gate of a first NMOS connects to a voltage source, and a source region of the first NMOS connects to a row decoder. A gate of the asymmetric NMOS connects to a drain region of the first NMOS. A drain region of the asymmetric NMOS connects to a column decoder, and a source region of the first asymmetric NMOS connects to a word line. A gate of a second NMOS connects to the column decoder, a source region of the second NMOS connects to a ground terminal and a drain region of the second NMOS connects to a source region of the first asymmetric NMOS.
