摘要:
An estimating unit estimates, when there is a request for data in a system in which an error checking unit of data is formed with a plurality of memories each of which is a dual memory having an independent address line, whether an error has occurred on the address line based on a result of an error checking for data related to the request. A control unit generates, when it is estimated that an error has occurred on the address line, error data of the data related to the request, and controls the memory in such a manner that one line of the dual memory is disabled by switching the data related to the request to generated error data.

A clock apparatus has a first clock unit, a backup power supply unit, a second clock unit, and a control unit. The first clock unit is used to count time, and the backup power supply unit is used to supply a backup power voltage to the first clock unit, when a general power supply unit does not supply a general power voltage to the clock apparatus. The second clock unit has a higher accuracy than the first clock unit. The control unit is used to adjust the time counted by the first clock unit in accordance with a specific period counted at the second clock unit, and the control unit is also used to control the resetting of an operation of the second clock unit, when the general power supply unit starts to supply the general power voltage to the clock apparatus after the general power supply unit has been stopped. Consequently, the clock apparatus has a high accuracy corresponding to the second clock unit, and has a low consumption power when the general power supply unit cannot to supply the general power voltage to the clock apparatus, so that an improved batter backup operation for the clock apparatus can be realized.

A soft error correction method is for a memory system having memory access controllers accessing memories for storing byte-sliced data in cycle synchronism, and a system controller receiving a memory access from an arbitrary one of MPUs and issuing a memory address to the memory access controllers. When a correctable error is detected in data read from one memory, an error address where the error was detected is held within a memory access controller, and an error notification is made to the system controller from the memory access controller. In response to the error notification, the memory access controller holds the error address from the system controller without intervention from the MPUs, and reads, corrects and rewrites the data to the error address.

To provide a technology of increasing the number of ranks of a memory module with a small change in architecture. A memory control device accessing a memory module having a plurality of ranks, includes an interface unit having selection signal lines via which to flow selection signals for selecting the ranks and address signal lines via which to flow address signals specifying addresses on the rank, and a control unit transmitting the signal for selecting the rank via part of the address signal line and via the selection signal line.
摘要:
Two data communication paths (first and second data communication paths) are provided between first and second data processor devices. First and second I/O ports are provided between the first data processor device and the first data communication path. Third and fourth I/O ports are provided between the second data processor device and the second data communication path. When failure occurs in the first data communication path, the data transmitted from the first data processor device is transferred to the second data processor device through the first I/O port, a bypass communication path, the second I/O port, the second data communication path, the third I/O port, a bypass communication path, and the fourth I/O port.
