Abstract

The present invention relates to a memory device and a method of fabricating the same. The memory device comprises a substrate, a tunnel dielectric film on the substrate, pairs of source and drain regions formed in the substrate, and a number of separate storage blocks between each pair of the source and drain regions. Each storage wire block includes a storage medium and a silicon dioxide layer. Two storage blocks are separated by an interval of at least 100 angstroms.
