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 14):
The method of  claim 13 , further comprising, after erasing the memory cell, reading the memory cell by:\n applying the first bias potential to the source line; applying a third bias potential to the control gate causing formation of an inversion layer in a substrate region below the control gate; applying a fourth bias potential to a drain region of the substrate causing a current above a threshold to flow from the drain region to the source line if the floating gate is in a predefined erased state; and sensing the current, if any, flowing from the drain region to the source line.
