Abstract:
Systems, methods, and devices that facilitate applying a predefined negative gate voltage to wordlines adjacent to a selected wordline associated with a memory cell selected during a read or verify operation to facilitate reducing adjacent wordline disturb are presented. A memory component can comprise an optimized operation component that can apply a predefined negative gate voltage to wordlines adjacent to a selected wordline associated with a memory cell selected for a read or verify operation, based at least in part on predefined operation criteria, to facilitate reducing adjacent wordline disturb in the selected memory cell to facilitate reducing a shift in the voltage threshold and maintain a desired operation window. The optimized operation component optionally can include an evaluator component that can facilitate determining whether a negative gate voltage applied to adjacent wordlines is to be adjusted to facilitate reducing adjacent wordline disturb below a predetermined threshold amount.
