Abstract
A non-volatile memory includes a memory cell having a first transistor and a second transistor, a driving circuit arranged to apply a read voltage to gates of the first and second transistors, and a signal output circuit arranged to output a signal associated with a first value or a signal associated with a second value, based on drain currents of the first and second transistors, in a read operation in which the read voltage is applied. The second transistor is constituted of a parallel circuit of a plurality of unit transistors, and gate width of each of the unit transistors is larger than that of the first transistor.
