Abstract:
A data backup method is provided. The data backup method includes maintaining a logical-to-physical table (L2P table) in a memory, where the L2P table records a plurality of physical addresses respectively corresponding to a plurality of first logical addresses and a plurality of trim marks; receiving a trim command, wherein the trim command indicates that data stored in one or more second logical addresses is invalid; according to the trim command, not clearing physical addresses respectively corresponding to the second logical addresses in the L2P table, and changing trim marks respectively corresponding to the second logical addresses from a first bit value to a second bit value; and when a predetermined condition is met, updating the L2P table according to the trim marks, and storing the updated L2P table into a rewritable non-volatile memory module.

Claim (Index 7):
The storage controller as claimed in  claim 6 ,\n wherein the processor receives a garbage collection command, wherein the garbage collection command indicates to execute a garbage collection operation to a first physical unit, wherein data stored in the first physical unit comprises second data and the first data stored in the one or more second logical addresses of the logical address section, wherein the processor executes the garbage collection operation to copy the second data of the first physical unit and the first data stored in the one or more second logical addresses to a second physical unit, wherein the processor updates the first logical-to-physical table according to a plurality of logical addresses and a plurality of physical addresses of the first data and the second data stored to the second physical unit, wherein the first trim marks of the first logical-to-physical table are not changed.
