A refresh signal is output in response to a refresh request generated at predetermined cycles, and a refresh operation is performed. The refresh operation ends when a conflict occurs between an access request and the refresh request. Consequently, an access operation corresponding to the access request can be started earlier with a reduction in access time. The access time can be reduced further by changing the end time of the refresh operation in accordance with the timing of supply of the access request. Since a test circuit for notifying the state of the refresh operation to exterior is formed, the operation margin of the refresh operation can be evaluated in a short time. As a result, it is possible to reduce the development period of the semiconductor memory.

A low-profile air conditioning register is provided with a retainer, a bezel and a plurality of downstream fins. The bezel is arranged in such a manner as to position a lower long side of an opening of a passage portion in a downstream than an upper long side. The angle formed between a flange portion and the ventilation direction of the retainer is equal to or more than 60°. Further, the length of a corresponding line to a short side of the opening in a surface which is orthogonal to the ventilation direction is equal to or less than 35 mm. Further a lower inner wall in the passage portion is inclined with respect to the ventilation direction in such a manner as to become lower toward a downstream side. The lower inner wall surface has a length equal to or less than 10 mm along a thickness direction of the flange portion.

The invention provides a vehicular shock absorbing body which absorbs a shock by a grid-like rib formed on a support plate portion and can inhibit a load point at an initial stage and a terminal stage, in a load-displacement (F-S) curve of the vehicular shock absorbing body. A shock absorbing body (40) used for absorbing a shock in a vehicle and made of a synthetic resin, is provided with a support plate portion (42), and a shock absorbing portion (45) formed in a grid shape on the support plate portion (42) by a plurality of thin ribs (44, 44), and plastically deforming at a time of applying a shock load so as to be absorbable a shock energy. A notch (a leading end side notch) 48 is formed between grid crossing points (46) in the thin rib (44) from a leading end side, and a notch (a root side notch) 50 is formed from a root side of the grid crossing points (46) so as to include the support plate portion (42), thereby inhibiting a load point from being generated at an initial stage and a terminal stage in the F-S curve.

A memory device includes: a memory cell array which stores two-dimensionally arranged data in a plurality of memory unit regions selected by an address; an internal address control unit which generates an internal address which selects a memory unit region according to an external address; and a decoder which decodes the internal address and selects a memory unit region. The plurality of memory unit regions store data arranged in a first direction from among two-dimensionally arranged data according to a least-significant bit group of the internal address and store data arranged in a second direction from among the two-dimensionally arranged data according to a most-significant bit group of the address. The internal address control unit successively generates an internal address corresponding to the scan direction according to a scan direction control signal which controls a plurality of scan directions including at least an oblique direction of the two-dimensionally arranged data.
