Abstract
Data storage circuits and components of such circuits constructed using nanotube switching elements. The storage circuits may be stand-alone devices or cells incorporated into other devices or circuits. The data storage circuits include or can be used in latches, master-slave flip-flops, digital logic circuits, memory devices and other circuits. In one aspect of the invention, a master-slave flip-flop is constructed using one or more nanotube switching element-based storage devices. The master storage element or the slave storage element or both may be constructed using nanotube switching elements, for example, using two nanotube switching element-based inverters. The storage elements may be volatile or non-volatile. An equilibration device is provided for protecting the stored data from fluctuations on the inputs. Input buffers and output buffers for data storage circuits of the invention may also be constructed using nanotube switching elements.
