It is shown that the two states('0' and '1') ofsingle-electronringmemory, which has a cyclic array of quantumdots, can be implemented byinputvoltagecontrollingthechargeson the islands.
Konstantin Likharev, at the State University of New York at Stony Brook, a co-inventor of the single-electron transistor, is working on ways to combine it with conventional transistors to make super-dense memory chips.
