Abstract
An integrated circuit that does not involve increase in power consumption or decrease in switching probability during a write operation that occur when a latch circuit using STT-MTJ device, etc. of the prior art is operated at high speed is provided. The integrated circuitincludes: a memory elementB where write occurs when a specified period τ has elapsed after a write signal is input; and a basic circuit elementA, which is an elementary device constituting a circuit and has a data retaining function, and characterized in that an operation frequency fin a first operation mode in the process of memory access of the basic circuit elementA satisfies the following relation:τ>λ(0<λ≦1).
