Abstract
A method for updating data in a non-volatile memory is provided. It is assumed that generally, the data to be written are sequential. After a pen drive receives a packet comprising to-be-updated data, it is determined whether the write-in address of the packet is in the same block with the last updated data to decide whether or not to copy back the un-updated data. Accordingly, unnecessary copy-back operations can be saved and the data updating efficiency can be improved.

A method for updating data in a non-volatile memory, comprising:
- receiving a packet comprising to-be-updated data;
- determining whether or not a write-in address of the packet is in a same block with a last-updated data, and whether or not the write-in address is series behind the last-updated data;
- and
- writing in data of the packet if the write-in address of the packet is in the same block with the last-updated data, and the write-in address is series behind the last-updated data.
