    Abstract: A method for improving an over erasing effect of a charge-trapping memory cell. The charge-trapping memory cell has a transistor, which has a first terminal coupled to a first bit line and a second terminal coupled to a second bit line. First, the method erases the charge-trapping memory cell. Then, after the charge-trapping memory cell is completely erased, the first bit line is electrically connected to the second bit line to make a voltage level of the first bit line equal a voltage level of the second bit line such that the voltage level of the first terminal of the transistor equals the voltage level of the second terminal of the transistor.

    Abstract: In one embodiment, a memory device includes an array of storage cells, multiple words lines, where each word line corresponds to a row in the array of storage cells, and multiple bit lines, where each bit line corresponds to a column in the array of storage cells. The device further includes a row decoder attached to the multiple word lines. The row decoder is operable to assert and to de-assert individual word lines. Each of the word lines has a head portion adjacent to where the word line is attached to the row decoder. The memory device supports a column decode sequence for accessing multiple storage cells within a row of the array. The column decode sequence both commences and terminates at or near the head portion of the word line corresponding to the row.

    Abstract: A method for accessing a memory sequentially. The memory has (m+1) bit lines and at least one row of transistors, wherein m is a positive integer. This method includes the following steps. First, voltage levels of first and second terminals of the transistors are equalized to a ground voltage in a pre-discharge period. Next, the voltage levels of the first and second terminals of the nth transistor are respectively transformed into a source voltage and a drain voltage in an nth reading period, and the voltage level of the second terminal of the (n+1)th transistor is transformed into an isolation voltage, wherein n is a positive integer smaller than m. Thereafter, the voltage levels of the first and second terminals of the mth transistor are respectively transformed into the source voltage and the drain voltage in an mth reading period. The source voltage equals the ground voltage.

    Abstract: Various methods and apparatuses permit high speed reads of memory. Portions of data are copied and stored on other word lines. By reading a copy of data that is stored on memory cells accessed by a word line that is already precharged, a latency specification can be met which does not allow time for precharging a second word line.

    Abstract: A circuit usable as a word line driver includes a driver that switches in response to a voltage on a control node, and a circuit supplying a voltage to the control node. The circuit that applies a voltage to control node provides a first static current tending to pull the control node up to a first source voltage, and provides a fighting current pulse in response to a signal selecting the driver to pull the control node down to a second source voltage, overcoming the first static current. In addition, a circuit provides a pull-up boost current on a transition of the signal selecting the driver that turns off the fighting current, and applies a boosting current pulse to the control node to assist pulling the control node quickly to the first source voltage.
