Abstract
According to one embodiment, an apparatus is capable of exchanging a frame with an external apparatus in a packet mode of a serial attached small computer system interface (SAS). The external apparatus includes a scrambler. The apparatus includes a descrambler and a controller. The descrambler is configured to descramble frame data scrambled by the scrambler. The controller is configured to, in a case where first frame data is received from the external apparatus, synchronize the descrambler with the scrambler using the first frame data and a first value that is to be scrambled by the scrambler to obtain the first frame data.
