Abstract: Provided is an overheat detection circuit that is capable of quickly outputting an overheated state detection signal in an overheated state without outputting an unintended erroneous output caused by disturbance noise, such as momentary voltage fluctuations in the power supply. The overheat detection circuit includes: a temperature sensor; a comparison section; and a disturbance noise removal section configured to output an overheated state detection signal to an output section after a predetermined delay time has elapsed. The delay time is reduced in proportion to temperature.

Abstract: Provided is a non-volatile semiconductor storage device which can be downsized with a simple circuit without impairing the function of an error correcting section, and a method of testing the non-volatile semiconductor storage device. An error correction circuit is configured to perform error detection and correction of merely the same number of bits as data bits, and a circuit for performing error detection and correction of check bits is omitted to downsize the circuit. A multiplexer for, in a testing state, replacing a part of the data bits read out from a storage element array with the check bits, and inputting the check bits to the error correction circuit is provided. Thus, error detection and correction of the check bits are performed to enable shipment inspection concerning the check bits as well.

Abstract: There are provided a vibration generation device and an electronic apparatus adapted to generate a variety of vibrations corresponding to a variety of situations without making the power consumption excessively high. The vibration generation device and the electronic apparatus according to the present embodiment is provided with two vibration motors having respective eccentric weights different in weight from each other, and drives a first vibration motor having a heavier one of the eccentric weights in the case of announcing a first event, for which notice with a strong vibration is necessary or effective. In contrast, in the case of announcing the second event, for which a quick response or a response performance is required, a second vibration motor having a lighter one of the eccentric weights is driven. The first events include incoming, coming of alarm time, a dynamic or important action, motion, and so on in a game. The second events include confirmation of input operation using a touch or a press on a screen of the electronic apparatus, a minute action, motion, and so on occurring in the game. Further, the correspondence between the vibration motors and the events is made selectable.
