    摘要: An instruction processor is employed which performs a cache coherence control according to a request from the storage controller. The storage controller is provided with a cache coherence control processing circuit, which performs the cache coherence control for the addresses which are the destinations of main memory accesses occurring with a data transfer. At the same time, the cache coherence control processing circuit performs the cache coherence control processing once for each cache line in the process of data transfer. The cache coherence control processing performed by software in connection with data transfer is obviated, improving the data transfer efficiency including the cache memory control and reducing limitations on program.

    摘要: A terminal resistance adjusting method adjusts a terminating resistance within a semiconductor integrated circuit. The method includes obtaining a comparison result by comparing a reference voltage and a voltage of a first node that is coupled to a first voltage via a current supply circuit, the first voltage being one of a power supply voltage and a ground voltage, controlling a monitoring resistor part which has a plurality of first resistors when making a calibration, so as to selectively couple the first resistors in parallel between the first node and a second voltage based on the comparison result, the second voltage being the other of the power supply voltage and the ground voltage, and controlling a terminating resistor part which has a plurality of second resistors when controlling the terminating resistance of the terminating part, so as to selectively couple the second resistors in parallel between a second node and the second voltage based on the comparison result similarly to the first resistors of the monitoring resistor part.

    摘要: A semiconductor device having at least three independently accessible memories, with at least one of the memories having a different memory capacity than the others. Separate selection signals are provided to the memories so that they can be independently activated. This allows the memories to be separately tested. When testing the semiconductor device, the memories are tested serially, except for the memory with the largest capacity, since this memory also has the longest test time. The memory with the longest test time is tested in parallel with the serially tested memories. This reduces the current that must be supplied by a test device to the semiconductor device during testing.
