An apparatus includes a nonvolatile memory, an interface that at least receives an erase command of the nonvolatile memory, a first controller that controls the nonvolatile memory to execute data erasing on the basis of the erase command output from the interface, an external input unit which is installed independently of the interface, a second controller that controls the nonvolatile memory to execute data erasing on the basis of an erase instruction signal output from the external input unit, and a change-over circuit that switches between connection of the first controller with the nonvolatile memory and connection of the second controller with the nonvolatile memory, wherein the second controller controls the nonvolatile memory to execute data erasing on the basis of the erase instruction when the connection of the second controller with the nonvolatile memory is established by the change-over circuit.

The quality and performance of the connectionless communications system are improved. When a BOM is received, the destination address DA of the L3-PDU stored in the payload of the BOM is retrieved, and the tag information is obtained from the DA (S11). The output message identifier MID is reserved (S12), and the tag information and output MID are assigned to the BOM (S13). Then, the tag information and output MID are written to the table. When a COM is received, the tag information and output MID are retrieved using the MID of the COM as a key, and the information is provided for the COM (S31 and S32). When an EOM is received, the tag information and output MID are retrieved using the MID of the EOM as a key, and the information is provided for the EOM (S41 and S42). Then, the output MID is released (S43).

Source data is stored in a source data storage unit and a comparing device compares source data with destination data stored in a destination data storage unit. A destination address compressing unit compresses destination address information, and other accounting parameters are output with some delay. An accumulating device accumulates information from the destination address compressing unit as an address. A source address compressing unit compresses or delays information from an accumulating unit, and then outputs information. A source address carrier compressing unit compresses or delays information from the source address compressing unit, and then outputs information. A destination address source address carrier re-compressing unit compresses or delays compressed information from the source address carrier compressing unit, and then outputs information. A period abnormality detecting circuit in an accounting unit validates transfer data and prevents a wrong accounting process from being performed.

A memory device that can include a power-supply voltage detector that detects power-supply voltage values and that outputs a detection result indicating which power-supply voltage value is detected; a data-rate setter that sets data rates corresponding to the detection result of the power-supply voltage detector, in synchronization with a rising edge or falling edge of a clock signal; and a memory cell array that performs reading/writing at the data rates set by the data-rate setter.

This invention relates to a functional device such as an FPGA carrying out a necessary function by programming, and provides a functional device, a function maintaining method and a function maintaining program which can maintain a function continuously. A plurality of function parts (FPGAs) is provided, and a function is maintained by switching from a function part, in which a failure is occurring, to a function part under stand-by. The plurality of function parts, a failure detection part (failure detection circuits) and a switching part (switching circuits) are provided, and a function part under operation and a function part under stand-by a reset. That is, the function part in which the failure is occurring is made into a stand-by state, and the function part which is under stand-by is made to operate. Therefore, the continuous function can be maintained without stopping the operation of a system due to the failure occurring in the function part, and the reliability of the system is heightened by the maintenance of the function.

摘要:
In a semiconductor storage apparatus, an internal address generation unit generates, when receiving successive first and second external addresses, from the second external address an internal address for selecting any of the memory cells connected to bit lines and word lines except the bit line and word line connected to a memory cell to be selected according to the first external address. When receiving the successive external addresses, a memory cell connected to the same bit line and word line is not continuously selected, and erroneous readout due to rewriting of a value of the memory cell in a non-selected state is suppressed.
