Abstract
A storage element is connected in series between the ground and a power supply terminal supplied with a power-supply voltage. A first transistor is connected in series to the storage element between the power supply terminal and the ground. A first control circuit supplies the gate of the first transistor with a first control voltage through the storage element. When the power-supply voltage has a voltage value for changing the resistance value of the storage element, the first control circuit supplies the gate of the first transistor with the first control voltage having a first voltage value. When the power-supply voltage has a voltage value for reading out the resistance value of the storage element, the first control circuit supplies the gate of the first transistor with the first control voltage having a second voltage value whose absolute value is greater than that of the first voltage value.
