Abstract

A memory is accessed based on memory access requests that has different data read sizes. A memory access method includes outputting each of read commands corresponding to the plurality of memory access requests to a memory at a timing that avoids conflict of read data output from the memory; generating an output start timing of the data read from the memory to an outside; retaining the data read from the memory in each of buffers, and causing any of the plurality of buffers to output data based on the output start timing; and delaying, in a case of receiving a subsequent memory access request during execution of memory access corresponding to a preceding memory access request, the output start timing of data from the buffer corresponding to the subsequent memory access request from the output start timing of data from the buffer corresponding to the preceding memory access request.
