Method of storing information in a memory cell

Abstract

A method of storing information in a memory cell. The method writes information via only the bit-line that is connected to a memory cell with respect to a word-line, and thus reduces the overall power consumption in the memory by reducing the unnecessary power consumption occurring from the change of voltage level in the bit-line that is not connected to a memory cell. To this end, a method of storing information in a memory cell having a sense amplifier which differentially amplifies a difference in voltage level between a pair of bit-lines is provided, the method comprising the steps of activating a word-line connected to the memory cell to be accessed, differentially amplifying the difference in voltage level between the pair of bit-lines coupled to the memory cell to be accessed, and selecting only one bit-line that is connected to the memory cell among the pair of bit-lines and rewriting the information via the one bit-line.
