  • Patent number: 7848146
    Abstract: A method for partial local self-boosting of a memory cell channel is disclosed. As a part of memory cell channel partial local self-boosting, an isolating memory cell located on a source side of a program inhibited memory cell is turned off and a gating memory cell located on a drain side of the program inhibited memory cell is used to pass a pre-charge voltage to the program inhibited memory cell to provide a pre-charge voltage to a channel of the program inhibited memory cell. Moreover, a pre-charge voltage is passed to a buffering memory cell located on the source side of the program inhibited memory cell to provide a pre-charge voltage to a channel of the buffering memory cell and the gating memory cell that is located on the drain side of the program inhibited memory cell is turned off. During programming, a program voltage is applied to the gate of the program inhibited memory cell where a channel voltage of the program inhibited memory cell is raised above a level raised by the pre-charge voltage.
