Abstract
A wrapping burst read determination unit determines whether or not a read request is a request of a wrapping read. If the read request is the request of the wrapping read, a memory address conversion unit extracts a plurality of addresses that includes an address in which payload data requested by the read request is stored, and designates a read out order of data from the plurality of addresses extracted. If the read request is the request of the wrapping read, a first data holding unit inputs first data read out from an address to which a forefront position in the read out order has been designated among the plurality of addresses, and stores the first data. If the read request is the request of the wrapping read, a data alignment unit, inputs trailing data read out from an address to which an end position in the read out order has been designated, and extracts payload data and an ECC which are correlated with each other from the first data and the trailing data.
