    摘要: Methods for sensing and memory devices are disclosed. One such method for sensing determines a threshold voltage of an n-bit memory cell that is adjacent to an m-bit memory cell to be sensed. A control gate of the m-bit memory cell to be sensed is biased with a sense voltage adjusted responsive to the determined threshold voltage of the n-bit memory cell.

    摘要: Methods for programming and memory devices are disclosed. One such method for programming includes initially biasing a subset of a plurality of control gates of a string of memory cells with a negative voltage, wherein the subset is less than all of the plurality of control gates of the string. The control gate of a selected memory cell is subsequently biased with a programming voltage during a programming phase.

    摘要: Memory arrays and their formation are disclosed. One such memory array has a string of series-coupled memory cells with a substantially vertical portion. A distance between adjacent memory cells at one end of the substantially vertical portion is greater than a distance between adjacent memory cells at an opposing end of the substantially vertical portion. For other embodiments, thicknesses of respective control gates of the memory cells and/or thicknesses of the dielectrics between successively adjacent control gates may increase as the distances of the respective control gates/dielectrics from the opposing end of the substantially vertical portion increase.

    摘要: Memory devices are disclosed, such as those that include a semiconductor-on-insulator (SOI) NAND memory array having a boosting plate. The boosting plate may be disposed in an insulator layer of the SOI substrate such that the boosting plate exerts a capacitive coupling effect on a p-well of the memory array. Such a boosting plate may be used to boost the p-well during program and erase operations of the memory array. During a read operation, the boosting plate may be grounded to minimize interaction with p-well. Systems including the memory array and methods of operating the memory array are also disclosed.

One method embodiment includes programming a memory cell to one of a number of different threshold voltage (Vt) levels, each level corresponding to a program state. The method includes programming a reference cell to a Vt level at least as great as an uppermost Vt level of the number of different Vt levels, performing a read operation on the reference cell, and determining a number of read reference voltages used to determine a particular program state of the memory cell based on the read operation performed on the reference cell.
