A method for garbage collecting for non-volatile memories are disclosed. The method includes steps: a) providing a SSD, connected to a host, containing a plurality of TLC blocks and SLC blocks; b) reading 3M TLC pages in a TLC block having data; c) moving valid data in the TLC blocks to at least one clean TLC block; d) sending a host program command of 1 page to the host; e) repeating step b) to step d) until valid data in 8 TLC blocks are moved; f) reading 1 SLC page in a SLC block having data; g) moving valid data in the SLC block to the at least one clean TLC block; h) sending a host program command of &#x3b1; page to the host; and i) repeating step f) to step h) until valid data in the SLC block having data are moved.

Method for gabage collecting for non-volatile memory

A method and a system for determining bit values in a non-volatile memory having a number of cells each for storing a bit value are disclosed. The method includes the steps of: a) providing a first test sensing voltage to the cells and calculating a cell count; b) providing another test sensing voltage to the cells and calculating a difference of the cell counts between this step and previous step; c) providing still another test sensing voltage and calculating another difference of the cell counts between this step and previous step; d) processing step c) for N times; e) calculating differential amounts of cell counts and assigning an index number to each group of cells; f) choosing a voltage as an updated sensing voltage.
