Abstract: In a semiconductor device, on a heat dissipation portion of a lead frame opposite to a mounting portion on which a semiconductor element is mounted, a thin molding portion having a thickness of about 0.02 mm to 0.3 mm is formed by a second molding resin which is a high-heat-dissipation resin. A scale-like portion on which scale-shaped projections are consecutively formed is provided over both sides across a resin boundary portion of the heat dissipation portion. The scale-like portion reaches abutting surfaces of an upper die and a lower die of a mold used in a molding process. Thus, the same void inhibition effect as with an air vent is obtained.

Abstract: A bandwidth between a second processor and a second memory is higher than a bandwidth between a first processor and a first memory. The first memory stores a read command from a host computer. The first processor analyzes a content of the read command, and in accordance with a result of the analysis, requests read data from the second processor. In response to the request from the first processor, the second processor reads the read data from one or more storage drives and stores the read data in the second memory. The second processor notifies the first processor that the read data is stored in the second memory. The first processor transfers the read data read from the second memory, to the host computer without storing the read data in the first memory.

Abstract: A storage system holds upper mapping information and lower mapping information. The upper mapping information manages an address relationship between a logical device upper layer accessed by a host and a logical device middle layer.

Each of the pieces of partial mapping information manages address information of a partial area in the logical device middle layer. The storage system writes, in response to a failure of first partial mapping information in the lower mapping information, new data that fills a first partial area in the logical device middle layer managed by the first partial mapping information, and regenerates the first partial mapping information.

Abstract: A storage controller manages a logical volume to which a host makes an access and which manages host data, an addition address space which is mapped with the logical volume and to which host data is added, and a physical address space which is mapped with the addition address space. In the addition address space, different address regions are allocated to respective parity groups. The storage controller selects, as an addition area of host data supplied from the host, an unoccupied address region in the addition address space. As the addition area, a region mapped to a normal status parity group in which data recovery is unnecessary is more preferentially selected than a region allocated to an abnormal status parity group in which data recovery is necessary.
