Abstract:
1. A method for partial local self-boosting of a memory cell channel, comprising: turning off an isolating memory cell located on a source side of a program inhibited memory cell; using a gating memory cell located on a drain side of said program inhibited memory cell, passing pre-charge voltage to said program inhibited memory cell to provide a pre-charge voltage to a channel of said program inhibited memory cell and passing pre-charge voltage to a buffering memory cell located on said source side of said program inhibited memory cell to provide a pre-charge voltage to a channel of said buffering memory cell; turning off said gating memory cell that is located on said drain side of said program inhibited memory cell; and during programming, applying a programming voltage to the gate of said program inhibited memory cell wherein a channel voltage of said program inhibited memory cell is raised beyond a level raised by said pre-charge voltage.
