Abstract
A semiconductor memory unit includes first to Nvariable resistance elements each having different resistance values according to values stored therein, wherein N is a natural number equal to or greater than 2; a reference resistance element having a first reference resistance value; and first to Ncomparison units which correspond to the first to Nvariable resistance elements, respectively, and each of which determines whether a resistance value of the corresponding variable resistance element is greater or less than a second reference resistance value, wherein the first to Ncomparison units are commonly coupled to the reference resistance element.
