DATA WRITING CONTROL DEVICE, DATA WRITING CONTROL METHOD, AND INFORMATION PROCESSING DEVICE

摘要

A data writing control device includes: a determination unit that determines whether a request from a requestor is a partial-write request for data and the partial-write is continuously performed to the same address; a transmission unit that, when the request from the requestor is the partial-write request for data and the partial-write is performed to an address different from an address of the previous partial-write, transmits a read request for data to the requestor; and a hold unit that holds write data included in the partial-write request and data indicating a rewritten location of the write data until read data corresponding to the read request for the data is received.
