Claim Text:
1. A resistance change memory comprising: a first memory cell including a resistance change element; a first bit line electrically coupled to the first memory cell; a sense amplifier which compares a reference current with a read current flowing through the first bit line, the sense amplifier including a first inverter, a second inverter, a first transistor, a second transistor, a third transistor and a fourth transistor, wherein: a fifth transistor which is electrically coupled between the fourth transistor and the first bit line and which has one of the conduction state and the cutoff state according to a fifth signal supplied to a gate of the fifth transistor; and a current generation circuit which supplies the reference current to the sense amplifier; wherein when the fourth transistor has the cutoff state, the first transistor has the conduction state.
