    摘要: A memory and a boundary searching method thereof are provided therein. When searching a boundary of a threshold voltage distribution of the memory, data errors resulted from tail bits of the memory would be corrected. Therefore, a sensing window could be broader, and the boundary of the threshold voltage distribution could be determined precisely.

    摘要: In response to a disagreement between a previously generated check code associated with previously programmed data bits and a more recently generated check code generated in response to a read command, the comparison process is changed, between i) a value representing accessed data and ii) a reference applied to such accesses to distinguish between logical levels. For example, the read bias arrangement and/or a read reference of a memory integrated circuit is changed.

    摘要: A method for designing a circuit layout of non-neighboring metal bit lines to reduce coupling effect in sensing operation is disclosed. The method comprises providing a memory array having a plurality of bit lines arranged sequentially, wherein every two adjacent bit lines are paired in the sensing operation of a memory cell in the memory array. The first embodiment is presented by assigning a first pair of the bit lines permuted with each other to create a non-neighboring bit line layout. The second embodiment is presented by inserting one of a second pair of the bit lines into a first pair of bit lines to separate the first pair of bit lines in layout design. The method further comprises shrinking the layout space between two adjacent non-paired bit lines. In this way, the method contributes to the reduction of metal bit line coupling effect without any trade off of integrated circuit density by modifying the circuit layout of metal bit lines to a non-neighboring bit line arrangement in a memory array.

    摘要: A method for detecting word line leakage in a memory device includes coupling a first plurality of word lines in the memory device to a voltage source while grounding a second plurality of word lines. Each of the second plurality of word lines is adjacent to a corresponding one of the first plurality of word lines. The method includes waiting for a period of time to allow the word lines to reach a predetermined read voltage level. The method also includes decoupling the first plurality of word lines from the voltage source and waiting for a second predetermined period of time to allow the first plurality of word lines to discharge. The method further includes sensing a current associated with the word lines, and comparing the current with a predetermined reference current which is selected for identifying a word line leakage condition associated with the first plurality of word lines.
