| 摘要 |
An electrically programmable memory device which has greater efficiency of electron injection from the channel to the floating gate comprises a substrate (401) having source (404) and drain (406) regions with a channel (410,413) therebetween; a floating gate structure over portions of the source (404) and drain (406) regions and the channel (410,413), which structure includes a dielectric layer (420) and a conductor layer (440) thereover, the channel under the floating gate (440) having both horizontal (410) and vertical (413) components.
