Claim 11:
12. The data accessing method according to claim 11, wherein M=3, N=3, and the data accessing method further comprises:
setting a reading voltage to be between Vt(1,1,0) and Vt(0,1,0) to perform the one-time reading operation related to the corresponding first bit of each multi-level cell;
setting reading voltages to be between Vt(1,1,1) and Vt(1,0,1), between Vt(1,0,0) and Vt(1,1,0), and between Vt(0,1,1) and Vt(0,0,1) respectively to perform the M reading operations related to the corresponding second bit of each multi-level cell; and
setting reading voltages to be between Vt(1,0,1) and Vt(1,0,0), between Vt(0,1,0) and Vt(0,1,1), and between Vt(0,0,1) and Vt(0,0,0) respectively to perform the N reading operations related to the corresponding third bit of each multi-level cell.
