Abstract:
An electrically erasable programmable nonvolatile memory cell includes a semiconductor substrate having a first substrate region and a trench region apart from the first substrate region in a lateral direction, a channel region between the first substrate region and the bottom portion of the trench region, an electrically conductive control gate insulated from and disposed over the first channel portion, an electrically conductive floating gate insulated from the bottom and sidewall portions of the trench region, an insulation region disposed over the second channel portion between the control gate and the second floating gate portion, an electrically conductive source line insulated from the floating gate and electrically connected to the trench region of the substrate, and an electrically conductive erase gate insulated from and disposed over a tip of the floating gate.

Claim (Index 15):
The method of  claim 13 , further comprising, after erasing the memory cell, programming the memory cell by:\n applying the first bias potential to the erase gate; and applying a fifth bias potential to a drain region of the substrate; applying a sixth bias potential higher than the fifth bias potential to the control gate; and applying a seventh bias potential higher than the sixth bias potential to the source line, causing a voltage of the floating gate to rise in accordance with the seventh bias potential due to capacitive coupling between the source line and the floating gate, and thereby causing electrons in a channel region of the substrate to gain energy and to be injected onto the floating gate.
