The semiconductor apparatus includes two or more sub-gates placed next to a main gate at a predetermined interval, and low concentration layers placed continuously from the ends of source/drain layers to near the end of the main gate, having a potential type same as that of the source/drain layers, and having an impurity concentration lower than that of the source/drain layers.

Abstract: When a storage system having a cache memory divided module is provided with independence of performance by allocating different cache areas to different disk volumes, the performance independence is deteriorated if a module is used for correlating a plurality of disk volumes. When a storage administrator uses a module for correlating plural disk volumes, a configuration management program in a management server outputs and displays a configuration change that may deteriorate the performance independence. To maintain performance independence, the management program changes the configuration of the cache area on the basis of a priority of the performance independence for each volume designated in advance by the administrator.

Abstract: A discrepancy between a management range of a user on a management computer, and a management range of the user in a storage, is detected with respect to a volume held in the storage. Storage management information of the management computer stores a correspondence between an identifier of a volume group, and an identifier of the user. When a plurality of volumes are designated as a managed object of the user, the management computer references the storage management information, and obtains, from the storage, an identifier of the volume group to which the plurality of designated volumes belong. Next, the management computer references the storage management information, and determines whether or not the obtained volume group is in the management range of the same user.

Abstract: An asynchronous reading circuit improves reliability of data read from a binary counter. Count data generated by a binary counter 101 according to a counting clock is converted into a gray code by a gray encoder. The count data represented by the gray code is sampled by a sampling circuit according to a timing signal asynchronous with the counting clock. The sampled count data is decoded into binary count data by a gray decoder.
