Abstract
A semiconductor storage device includes a variable resistive element, which changes a resistance value according to a polarity and a magnitude of an applied voltage, as a memory element. The semiconductor storage device includes a standby mode in which a power source voltage or a ground voltage is applied to both of a word line and a bit line. The semiconductor storage device includes a data write mode in which a voltage difference equal to or more than a first voltage is applied between the word line and the bit line. The semiconductor storage device includes a read mode in which a voltage difference smaller than the first voltage is applied between the word line and the bit line by changing only one voltage of the word line and the bit line which is applied in the standby mode, and data written in the memory element is read.
