    摘要: A memory and method for charging a word line thereof are disclosed. The memory includes a first word line driver, a first word line and a first switch. The first word line driver is connected to a first operational voltage for receiving a first control signal. The first word line comprises a start terminal connected to an output terminal of the first word line driver. The first switch is connected to a second operational voltage and an end terminal of the first word line. The second operational voltage is not smaller than the first operational voltage. When the first word line driver is controlled by the first control signal to start charging up the first word line, the first switch is simultaneously turned on to provide another charging path for the first word line until the first word line is charged to the first operational voltage.

    摘要: Over-erasure induced noise on a data line in a nonvolatile memory that couples into an adjacent data line is mitigated by using twisted data lines and differential sensing amplifiers. Noise coupled into data lines is compensated by similar noise coupled into reference data lines and cancelled in the differential sensing amplifiers.

    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: An accessing method for a charge trapping memory including memory cells and tracking cells for storing expected data. The method includes the following steps. In a specific time first, the expected data is written into the tracking cells and the memory cells are not being programmed, read or erased. Next, the data stored in the tracking cells is sensed as read data according to a present reference current. Then, the present reference current is adjusted to an adjusted reference current according to a difference between the read data and the expected data so that the data stored in tracking cells is sensed as corresponding with the expected data according to the adjusted reference current. Thereafter, the memory cells are read according to the adjusted reference current.
