Abstract:
In reading of a memory unit, an read failure operation due to variation in characteristic of a transistor in a dynamic load is reduced. A read circuit that reads a voltage obtained by a voltage division of a dynamic load unit and the memory unit as an output of the memory unit includes the dynamic load unit having one end connected to a side of a power supply and the other end connected to a side of the memory unit, and a feedback unit that, by a feedback of the voltage obtained by the voltage division that is divided between the dynamic load unit and the memory unit, holds the voltage obtained by the voltage division. The dynamic load unit has an array structure in which a plurality of resistive memory elements are connected in series, in parallel, or in series-parallel. The dynamic load unit has the array structure of the resistive memory elements and this structure can suppress the read failure operation due to the variation in dynamic load.
