    摘要: Roughly described, a memory includes first and second target memory cells in a plurality of electrically adjacent memory cells all sharing a word line. The two target memory cells are separated from each other by at least one additional memory cell, and first current path terminals of the target memory cells bracket second current path terminals of the target memory cells electrically along the word line. The two target memory cells are read by connecting the first current path terminals of the two target memory cells to ground, precharging the second current path terminals of the two target memory cells to respective precharged states, and while both second current path terminals are in their respective precharged states, initiating a sense operation to read both the first and second target memory cells substantially simultaneously.

    摘要: A controlling output buffer slew rate method and an output buffer circuit for a memory device is provided. The output buffer include an output stage formed by a PMOS transistor and a NMOS transistor electrically connected in series, a pre-driver for respectively controlling each gate terminal of the PMOS transistor and the NMOS transistor in order to bring these transistors to the turning-on threshold, a first wire, for transmitting a pull-up signal, coupled between the output stage and the pre-driver, and a second wire, for transmitting a pull-down signal, coupled between the output stage and the pre-driver. After a DATA signal transition (logic state is changed from “H” to “L” or “L” from to “H”), the PMOS or NMOS transistor is turned off first, and then the NMOS or PMOS transistor is turned on due to the time difference between the pull-up signal and the pull-down signal.

    摘要: A memory device operates according to a method for reading includes pre-charging a first set of selected bit lines to a pre-charge voltage and sensing data from the cells coupled to the first set of selected bit lines. Then, residual charge is transferred from the first set of selected bit lines to corresponding members of a second set of selected bit lines. The second set of selected bit lines, having an initial charge transferred from the first set, is then pre-charged to the pre-charge voltage. The data from the cells coupled to the second set of selected bit lines it is then sensed. In embodiments described herein, the read operation occurs in a burst read mode, where a volume of data having consecutive addresses is read.
