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: A pressure sensor which detects variation in pressures, the pressure sensor including a cantilever which is bent according to a pressure difference between the inside and the outside of a cavity in a sensor main body, and an intra-lever gap which is formed on a proximal end portion of the cantilever. The proximal end portion is partitioned into a first support portion and a second support portion by an intra-lever gap in a second direction orthogonal to a first direction in which the proximal end portion and a distal end portion are connected to each other in plan view. A doped layer which is provided on a portion of the first and second support portions forms a first displacement detection portion and a second displacement detection portion. Lengths of the first and second displacement detection portions are shorter than those of the first and second supports along the second direction.
