A memory capable of suppressing reduction of a reading voltage in data reading regardless of dispersion in a manufacturing process is provided. This memory comprises charge storage means, a first field-effect transistor and data determination means. The memory sets a voltage between a control terminal and a remaining first terminal of the first field-effect transistor to a threshold voltage for bringing the first field-effect transistor into an OFF-state in the vicinity of a boundary state between ON- and OFF-states through the threshold voltage of the first field-effect transistor.
