Abstract
A memory system includes a packet protection circuit. The packet protection circuit includes a plurality of first CRC calculation circuits, each configured to calculate a CRC of M-byte data, where M is an integer greater than or equal to 1 and less than N, where N is an integer greater than or equal to 2, a first selector configured to output a CRC calculation result of one of the first CRC calculation circuits, and a second CRC calculation circuit configured to calculate a CRC of L-byte data, where L<N, where L=N×Z, and Z is an integer greater than 1, and add the CRC of L-byte data to the CRC calculation result output from the first selector to generate a first CRC that is compared with a second CRC to detect an error in a data packet transmitted between the host interface unit and the host device.
