摘要： Methods for determining a program window and memory devices are disclosed. One such method for determining the program window measures an amount of program disturb experienced by a particular state and determines the program window responsive to the amount of program disturb.

摘要： Embodiments of the present disclosure provide methods, devices, modules, and systems for programming multilevel non-volatile multilevel memory cells. One method includes increasing a threshold voltage (Vt) for each of a number of memory cells until the Vt reaches a verify voltage (VFY) corresponding to a program state among a number of program states. The method includes determining whether the Vt of each of the cells has reached a pre-verify voltage (PVFY) associated with the program state, selectively biasing bit lines coupled to those cells whose Vt has reached the PVFY, adjusting the PVFY to a different level, and selectively biasing bit lines coupled to cells whose Vt has reached the adjusted PVFY, wherein the PVFY and the adjusted PVFY are less than the VFY.
