Abstract
A storage device includes a storage controller, non-volatile memory, volatile memory and a communication interface configured to connect to external volatile memory of a host system. The storage controller is configured to receive data from the host system for storing in the non-volatile memory, buffer the data in the volatile memory, obtain parity data corresponding to the buffered data from an external volatile memory within the host system, compute XOR parity data for the buffered data based on the parity data and the buffered data, store the computed XOR parity data on the external volatile memory, and write the data from the host to the non-volatile memory.
