Abstract
A partial data changing method of a memory controller includes receiving a request to change partial data from a host; detecting an error of old data, the old data being partial data read from a memory device using an error detection code; if the old data is not erroneous, calculating a data difference between new data provided from the host and the old data, and calculating a new parity using the data difference and an old parity read from the memory device; and storing the new data and the new parity at the memory device.
