摘要： A method for programming a first memory cell in a memory array. In a specific embodiment, each memory cell has a drain, a source, a channel, and a control gate overlying a charge storage material and the channel. The source of the first memory cell is coupled to the drain of a second memory cell. A voltage is applied to the drain of the first memory cell, and the source of the second memory cell is grounded. The method includes floating the drain of the second memory cell and the source of the first memory cell and turning on the channels of the first and second memory cells, effectively forming an extended channel region. Hot carriers are injected to the charge storage material of the first cell to program the first memory cell. The extended channel lowers electrical fields and reduces punch through leakage in unselected memory cells.

摘要： A memory apparatus, a controller, and a method thereof for programming non-volatile memory cells are provided. The memory apparatus includes a plurality of memory cells, wherein each memory cell shares a source/drain region with a neighboring memory cell. The method utilizes a compensation electron flow applied into a source/drain region between two memory cells to provide enough electron flow to program one of the two memory cells, even under the circumstances that the other memory cell has a greater threshold voltage, such that the dispersion of the programming speed of the memory cells is reduced.
