Abstract:
An erasable programmable non-volatile memory includes a first-type well region, three doped regions, two gate structures, a blocking layer and an erase line. The first doped region is connected with a source line. The third doped region is connected with a bit line. The first gate structure is spanned over an area between the first doped region and the second doped region. A first polysilicon gate of the first gate structure is connected with a select gate line. The second gate structure is spanned over an area between the second doped region and the third doped region. The second gate structure includes a floating gate and the floating gate is covered by the blocking layer. The erase line is contacted with the blocking layer. The erase line is located above an edge or a corner of the floating gate.
