Patent Images
1. A hybrid memory circuit, comprising:
- an electromechanical memory cell having at least two electrodes and in which at least one of the two electrodes is formed of a plurality of nanotubes and in which the first electrode crosses the second electrode;
an access circuit constructed of semiconductor circuit elements for providing addressing the memory cell circuit so as to activate the electromechanical memory cell for read and write operations, wherein write operations cause the one electrode formed of a plurality of nanotubes to deflect to a physical state corresponding to an information state, and wherein read operations do not change the deflected state.

Abstract
A hybrid memory system having electromechanical memory cells is disclosed. A memory cell core circuit has an array of electromechanical memory cells, in which each cell is a crossbar junction at least one element of which is a nanotube or a nanotube ribbon. An access circuit provides array addresses to the memory cell core circuit to select at least one corresponding cell. The access circuit is constructed of semiconductor circuit elements.
