    摘要： Each semiconductor memory module is divided into a plurality of access control units, and a service adapter copies the contents of the memory of the semiconductor memory module in which a memory error has occurred, to a spare semiconductor memory module one access control unit at a time. It is thus possible to evacuate the contents of the memory of the semiconductor memory module in which the memory error has occurred without stopping the semiconductor disk apparatus simply by adding the spare semiconductor disk apparatus. Since the copying operation is executed one access control unit at a time, a resource manager can conduct exclusive control also one access control unit at a time. A host apparatus therefore can access an access control unit portion which is not the object of copying even in the process of copying. In other words, the copying operation exerts no deleterious influence on the access of the host apparatus.

    摘要翻译： 每个半导体存储器模块被分成多个访问控制单元，并且服务适配器将其中发生存储器错误的半导体存储器模块的存储器的内容复制到备用半导体存储器模块一次存取控制单元 。 因此，可以简单地通过添加备用半导体盘装置来排出已经发生存储器错误的半导体存储器模块的存储器的内容而不停止半导体盘装置。 由于一次执行一个访问控制单元的复制操作，所以资源管理器一次也可以执行一个访问控制单元的排他控制。 因此，即使在复制过程中，主机设备也可以访问不是复制对象的访问控制单元部分。 换句话说，复制操作对主机设备的访问没有有害的影响。
