    Abstract: Provided is a fabrication method of a non-volatile memory device having a zigzag body wiring. First word lines and second word lines are formed on a substrate, wherein the first word lines and the second word lines are arranged periodically and extend in a first direction. Bit lines are formed over the first and second word lines, wherein a first distance from the first word lines to the substrate is smaller than a second distance from the second word lines to the substrate.

    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.

    Abstract: An memory management method, a memory storage device and a memory controlling circuit unit are provided. The method comprises: obtaining a threshold voltage distribution of memory cells, wherein the threshold voltage distribution comprises a plurality of states, and each of the states represents a storage status; determining whether a width of a gap window between two neighboring states among the states is less than a threshold value; and if the width of the gap window is less than the threshold value, eliminating one of the two neighboring states.
