Abstract
Circuit arrays having cells with combinations of transistors and nanotube switches. Under one embodiment, a circuit array includes a plurality of cells arranged in an organization of words, each word having a plurality of bits. Each cell is responsive to a bit line, word line, reference line, and release line. Bit lines are arranged orthogonally relative to word lines and each word line and bit line are shared among a plurality of cells. Each cell is selectable via the activation of the bit line and word line. Each cell includes a field effect transistor coupled to a nanotube switching element. The nanotube switching element is switchable to at least two physical positions at least in part in response to electrical stimulation via the reference line and release line. Information state of the cell is non-volatilely stored via the respective physical position of the nanotube switching element. Under another embodiment, a circuit array includes a plurality of cells arranged in an organization of words, each word having a plurality of bits. Each cell is responsive to a bit line, word line, and reference line. Each word line and bit line are shared among a plurality of cells. Each cell …
