IPC: G06F11/10
Filed: 2001-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for transferring a check sum to a different memory position without stopping the execution of an application. SOLUTION: A plurality of memory systems 139a-139c and a system manager are used to transfer the check sum in a memory. The first memory system has a first memory position correlating to check sum indicators 161a-161c. The check sum indicators identify the memory system storing the check sum having a value currently stored in the first position. The system manger dynamically transfers the check sum to an addressed memory position and renews it so that the check sum indicators can identify the memory system at the addressed memory position. After transferring the check sum, the system manager renews the check sum using a value stored in the old memory position. As a result, the check sum at the check sum addressed position is effectively renewed to permit the recovery of data.
