Abstract:
In a data read-and-write controlling device, without waiting for confirmation that data is written in a RAM, data is written in a WER and an ADR, and at the same time, address information of the data is written in the RAM write-information table. That is, the data read-and-write controlling device associates an address retained at a data register of a write controlling unit with the value (a write request is present=“1”) of a write request that makes a request for writing data in the RAM, the value being retained in a write request register, and then causes the result to be stored in the RAM write-information table as the address information.
