NON-VOLATILE MEMORY CELL AND METHOD OF MANUFACTURING THE SAME |
摘要 |
A non-volatile memory cell includes a substrate, an erase gate disposed on the substrate and having a top plane, two floating gates disposed respectively at both sides of the erase gate, two control gates disposed respectively on two floating gates, and two select gates disposed respectively at outer sides of the two floating gates, where the two select gates have tilted top planes which are symmetric to each other. |

1. A non-volatile memory cell, comprising:
a substrate; two stack structures disposed on said substrate, wherein each said stack structure comprises a floating gate and a control gate on said floating gate; an erase gate disposed on said substrate between said two stack structures, wherein said erase gate comprises a top plane; and two select gates disposed respectively at outer sides of said two stack structures, wherein said two select gates comprise tilted top planes which are symmetric to each other. |
