Abstract
A pre-charging method applied in DRAM which includes steps of: enabling wordlines in an active array and an reference array; disabling the wordlines in the active array; equilibrating digital lines in the active array and the reference array to half of a power supply voltage; storing the half of the power supply voltage in reference cells of the reference array; disabling the wordlines in the reference array; pre-charging the digital lines in the active array and the reference array to the power supply voltage; and enabling the wordlines in the active array and the reference array at the same time.
