The present invention provides a storage device including a plurality of first memories, a controller, and a second memory. The controller controls the plurality of first memories so that first and second data chunks are distributively stored in the plurality of first memories. The controller generates a first intermediate parity based on the first data chunk, which is processed immediately before the second data chunk. When the second data chunk is not a data chunk which is processed last and the first intermediate parity is buffered in the second memory, the controller generates a second intermediate parity based on the first intermediate parity buffered in the second memory and the second data chunk, and outputs the second intermediate parity to the second memory so that the second intermediate parity is buffered in the second memory without being stored in a third memory inside the controller. According to the present invention, latency for generating the parity may decrease. COPYRIGHT ...
