Claim 13:
14. The data search method according to claim 13, wherein the first transistor and the second transistor are both multi-level cells (MLC), the first number is equal to “4”, the first number of voltage distributions comprise a first voltage distribution, a second voltage distribution, a third voltage distribution and a fourth voltage distribution, and the data search method comprising:
programming the first threshold voltage to have the first voltage distribution;
programming the second threshold voltage to have the first voltage distribution;
encoding the stored data as “don't care” according to the first threshold voltage and the second threshold voltage;
determining that the mismatch distance is “0”; and
determining that the search data completely matches the stored data.
