摘要:
A semiconductor integrated circuit device, has a first variable resistor element and a second variable resistor element whose resistances are changed complementarily depending on a current; and a current path switching circuit that supplies said current from a power supply by switching between current paths according to whether a normal operation mode or a read mode is input externally, wherein said power supply is turned off and then turned on again in said normal operation mode, and in this state, data corresponding to the relationship between the magnitudes of the resistances of said first variable resistor element and said second variable resistor element is read in said read mode.
