    Abstract: An integrated circuit and a code generating method are described. The integrated circuit includes a plurality of field effect transistors, a plurality of sense-amplifiers, and a processing circuit. Each field effect transistor is configured to represent an address in a mapping table and includes a source, a drain, a channel and a gate. Each sense-amplifier is connected to the drain and configured to sense an electric current from the drain and identify a threshold voltage of the corresponding field effect transistor. The processing circuit is configured to categorize each of the threshold voltages identified by the corresponding sense-amplifiers into a first state and a second state and mark the state of each of the threshold voltages at the corresponding address in the mapping table.

First inter-poly dielectric films are disposed on the substrate and respectively beneath the first word lines. Second inter-poly dielectric films are disposed on the substrate and respectively beneath the second word lines, wherein the first inter-poly dielectric films are thinner than the second inter-poly dielectric films. A floating gate is disposed between the substrate and each of the first and second inter-poly dielectric films. A tunnel oxide film is disposed between the substrate and each of the floating gates. Bit lines are disposed above the first and second word lines and extended along a second direction different from the first direction.

    Abstract: A memory management method, a memory storage device and a memory controlling circuit unit are provided. The method comprises: obtaining an erased state voltage of a first memory cell and a programmed state voltage of the first memory cell, where the first memory cell is operated in a first programming mode; and operating the first memory cell in a second programming mode if a width of a gap between the erased state voltage and the programmed state voltage is larger than a first threshold value. Accordingly, the reliability of the first memory cell may be improved.

    Abstract: A memory management method, a memory storage device and a memory control circuit unit are provided. The method comprises: obtaining a first threshold voltage distribution of memory cells; grouping the first threshold voltage distribution to a plurality of first threshold voltage groups; obtaining a second threshold voltage distribution of the memory cells; grouping the second threshold voltage distribution to a plurality of second threshold voltage groups; allocating a memory cell among the memory cells to a virtual block if a threshold voltage pair of the memory cell belongs to a specific group of the first threshold voltage groups and a specific group of the second threshold voltage groups, such that the first memory cell is operated under a specific-level cell mode. Accordingly, the reliability of memory cells may be improved without significantly sacrificing the capacity of the rewritable non-volatile memory module.
