    Abstract: Systems and methods of sequentially accessing memory cells in a nonvolatile memory device (NVM) are provided. The NVM has a plurality of strings and a common signal line coupled to the plurality of strings. Each string includes a plurality of memory cells and a selection transistor coupled between the plurality of memory cells and the common signal line. A command that accesses multiple memory cells is received, a voltage is applied to a first selection transistor of a first string to electrically connect the common signal line to the first string, a pulse is applied for a predetermined time period to selection transistors of other strings, and memory cells of the first string are accessed. Advantages such as removal of boosting charges from unselected strings prior to sequentially accessing memory cells from selected strings can improve performance and reliability of NVM-based systems.

    Abstract: Methods of operating memory systems and nonvolatile memory devices include performing error checking and correction (ECC) operations on M pages of data read from a first “source” portion of M-bit nonvolatile memory cells within the nonvolatile memory device to thereby generate M pages of ECC-processed data, where M is a positive integer greater than two (2). A second “target” portion of M-bit nonvolatile memory cells within the nonvolatile memory device is then programmed with the M pages of ECC-processed data using an address-scrambled reprogramming technique, for example.
