Random telegraph signal noise reduction scheme for semiconductor memories
Abstract:
Embodiments are provided that include a method including providing a first pulsed gate signal to a selected memory cell, wherein the pulsed gate signal alternates between a first voltage level and a second voltage level during a time period and sensing a data line response to determine data stored on the selected memory of cells. Further embodiments provide a system including a memory device, having a regulator circuit coupled to a plurality of access lines of a NAND memory cell, and a switching circuit configured to sequentially bias at least one of the plurality of the access lines between a first voltage level and a second voltage level based on an input signal.
