In a system operations management apparatus, a burden to a system administrator when providing a decision criterion in detection of a failure in the future is reduced. The system operations management apparatus 1 includes a performance information accumulation unit 12, a model generation unit 30 and an analysis unit 31. The performance information accumulation unit 12 stores performance information including a plurality of types of performance values in a system in time series. The model generation unit 30 generates a correlation model including one or more correlations between the different types of performance values stored in the performance information accumulation unit 12 for each of a plurality of periods having one of a plurality of attributes. The analysis unit 31 performs abnormality detection of the performance information of the system which has been inputted by using the inputted performance information and the correlation model corresponding to the attribute of a period in which the inputted performance information has been acquired.

A substrate including a semiconductor layer, where characteristics of an element can be evaluated with high reliability, and an evaluating method thereof are provided. A substrate including a semiconductor layer of the invention has a closed-loop circuit in which an antenna coil and a semiconductor element are connected in series, and a surface of an area over which the circuit is formed is covered with an insulating film. By using such a circuit, a contactless inspection can be carried out. Further, a ring oscillator can be substituted for the closed-loop circuit.

Provided is a semiconductor device with a novel structure in which stored data can be retained even when power is not supplied, and which does not have a limitation on the number of writing. The semiconductor device includes both a memory circuit including a transistor including an oxide semiconductor (in a broader sense, a transistor whose off-state current is sufficiently small), and a peripheral circuit such as a driver circuit including a transistor including a material other than an oxide semiconductor (that is, a transistor capable of operating at sufficiently high speed). Further, the peripheral circuit is provided in a lower portion and the memory circuit is provided in an upper portion, so that the area and size of the semiconductor device can be decreased.

It is an object to provide a semiconductor device with a novel structure in which stored data can be held even when power is not supplied and there is no limitation on the number of writings. A semiconductor device includes a second transistor and a capacitor provided over a first transistor. A source electrode of the second transistor which is in contact with a gate electrode of the first transistor is formed using a material having etching selectivity with respect to the gate electrode. By forming the source electrode of the second transistor using a material having etching selectivity with respect to the gate electrode of the first transistor, a margin in layout can be reduced, so that the degree of integration of the semiconductor device can be increased.

The invention provides a novel memory for which process technology is relatively simple and which can store multivalued information by a small number of elements. A part of a shape of the first electrode in the first storage element is made different from a shape of the first electrode in the second storage element, and thereby voltage values which change electric resistance between the first electrode and the second electrode are varied, so that one memory cell stores multivalued information over one bit. By partially processing the first electrode, storage capacity per unit area can be increased.
