Abstract
A non-volatile memory based storage system capable of directly overwriting without using redundancy and its writing method are provided. The invention first writes data into a register. Then, a portion of MCF information of the decoded logical writing destination address is taken as a physical writing address and used to determine whether there is data in a block corresponding to the physical writing address. If yes, a new swap block is taken out from a swap table and at least one record of data in the register is written into the swap block.
