ABSTRACT:
Provided is a memory device formed using quantum devices and a method for manufacturing the same. A memory device includes a substrate; a source region and a drain region formed in the substrate so as to be separated from each other by a predetermined interval. A memory cell is formed on the surface of the substrate to connect the source region and the drain region, and has a plurality of nano-sized quantum dots filled with material for storing electrons. A control gate is formed on the memory cell and controls the number of electrons stored in the memory cell. It is possible to embody a highly efficient and highly integrated memory device by providing a memory device having nano-sized quantum dots and a method for manufacturing the same.
