Abstract:
1. An electronic circuit, comprising: a first transistor that has a first drain, a first source, and a first gate; a second transistor that has a second drain, a second source, and a second gate that is connected to the first gate; a third transistor that is connected between the first gate and one of the first drain and the first source; and a fourth transistor that is connected between one of the first drain and the first source and one of the second drain and the second source, a programming current that determines a first conduction state of the first transistor and a second conduction state of the second transistor, a first part of the programming current flowing through the first transistor during a first period, a second part of the programming current flowing through the second transistor during the first period, and at least a part of a reproduction current whose level corresponds to the first conduction state flowing through the second transistor during a second period.
