Patent ID: 7282731

Claim:
A rewritable quantum supermemory having serial access, the supermemory comprising: a memory cell and first and second supply electrodes providing access to the memory cell, the memory cell including a plurality of clusters each having a tunnel-transparent shell, each cluster has a distinguished size determined within the range 7.25 nm≦r≦29.0 nm, the gap between clusters being less than or equal to 7.25 nm, the spacing between the electrodes being greater than 7.25 nm; wherein the clusters are arranged in a plurality of layers including a top cluster layer and a bottom cluster layer, each cluster layer including clusters arranged in rows and columns, the clusters of each cluster layer being in contact with corresponding clusters of adjacent cluster layers; wherein the first supply electrode extends in a first direction over the cluster layers and contacts the clusters in odd numbered columns of a given row of the top cluster layer; wherein the second supply electrode extends in the first direction over the cluster layers and contacts the clusters in an even numbered columns of the given row of the top cluster layer; wherein the clusters in the given row are integrated in a group in the form a series circuit; an input electrode connected to an input of the series circuit; and an output electrode connected to the output of the series circuit.
