Unlike their digital cousin, the FPGA , the devices tend to be more application driven than general purpose as they may be current mode or voltage mode devices. For voltage mode devices, each block usually contains an operational amplifier in combination with programmable configuration of passive components. The blocks can, for example, act as summers or integrators. FPAAs usually operate in one of two modes continuous time and discrete time . Discrete time devices possess a system sample clock. In a switched capacitor design, all blocks sample their input signals with a sample and hold circuit composed of a semiconductor switch and a capacitor. This feeds a programmable op amp section which can be routed to a number of other blocks. This design requires more complex semiconductor construction.

FieldProgrammable Nanowire Interconnect often abbreviated FPNI is a new computer architecture developed by Hewlett Packard . This is a defect tolerant architecture, using the results of the Teramac experiment. Details The design combines a nanoscale crossbar switch structure with conventional CMOS to create a hybrid chip that is simpler to fabricate and offers greater flexibility in the choice of nanoscale devices. The FPNI improves on a fieldprogrammablegatearray FPGA architecture by lifting the configuration bit and associated components out of the semiconductor plane and replacing them in the interconnect with nonvolatile switches, which decreases both the area and power consumption of the circuit while providing up to eight times the density at less cost. This is an example of a more comprehensive strategy for improving the efficiency of existing semiconductor technology placing a level of intelligence and configurability in the interconnect can have a profound effect on integrated circuit performance, and can be used to significantly extend Moore s Law without having to shrink the transistors.

A field emitter array FEA is a particular form of field electron emission large area field electron source . FEAs are prepared on a silicon substrate by lithographic techniques similar to those used in the fabrication of integrated circuits. Their structure consists of a very large number of individual, similar, small field electron emitters, usually organized in a regular two dimensional pattern. FEAs need to be distinguished from film or mat type large area sources, where a thin film like layer of material is deposited onto a substrate, using a uniform deposition process, in the hope or expectation that as a result of statistical irregularities in the process this film will contain a sufficiently large number of individual emission sites. Spindt arrays The original form of FEA was the Spindt array , in which the individual field emitters are small sharp molybdenum cones. Each is deposited inside a cylindrical void in an oxide film, with a counterelectrode deposited on the top of the film. The counterelectrode called the gate contains a separate circular aperture for each conical emitter ..., a Spindt tip can create a high electric field at a relatively low voltage, and thus emits significant amounts of current at relatively low gate voltages less than 100 V .

Orphan date November 2010 Programmed magnets , or correlated magnets , are magnetic structures that incorporate correlated patterns of magnet s with alternating polarity, designed to achieve a desired behavior. Correlated magnet pairs can be programmed to attract or repel with a prescribed force and engagement distance, or, to attract or repel at certain a spatial orientation. Correlated magnets can be programmed to interact only with other magnetic structures that have been coded to respond. Correlated magnets can even be programmed to attract and repel at the same time. The programmable behavior is achieved by creating multipole structures comprising multiple magnetic elements maxels of varying size, location, orientation, and saturation. Programmed magnets can be programmed, or coded, by varying the polarity and or field strengths of each source of the arrays of magnetic sources that make up each structure. The resulting magnetic structures can be one dimensional, two dimensional, three dimensional, and even four dimensional if produced using an electromagnetic array. Correlated magnetic structures can be developed from ferrites, rare earth materials, ceramics, and electromagnet s alike, and the correlation effects are scalable from very large permanent magnets to nanometer scale devices ref http www.nanowerk.com news newsid 12983.php ref . Multipole magnetic devices may be constructed from discrete permanent magnets, or by exposing heated magnetizable material to a coded magnetic field.

Correlated Magnetics Research, LLC, was formed to pursue research and development of the Coded Magnets TM technology and to license the technology to business entities across industry. More than 65 patents have been filed for the technology in the U.S. and around the world. Correlated Magnetics Research LLC has trademarked the name Coded Magnets for the ... more details

Unreferenced date December 2009 A macrocell array is an approach to the design and manufacture of Application specific integrated circuit ASIC s. Essentially, it is a small step up from the otherwise similar gatearray , but rather than being a prefabricated array of simple logic gates, the macrocell array is a prefabricated array of higher level logic functions such as Flip flop electronics flip flop s, Arithmetic logic unit ALU functions, Hardware register register s, and the like. These logic functions are simply placed at regular predefined positions and manufactured on a wafer electronics wafer , usually called master slice . Creation of a circuit with a specified function is accomplished by adding metal interconnects to the chips on the master slice late in the manufacturing process, allowing the function of the chip to be customised as desired. Macrocell array master slices are usually prefabricated and stockpiled in large quantities regardless of customer orders. The fabrication according to the individual customer specifications may be finished in a shorter time compared with standard cell or full custom design. The macrocell array approach reduces the Photomask mask costs since fewer custom masks need to be produced. In addition manufacturing test tooling lead time and costs are reduced since the same test fixtures may be used for all macrocell array products manufactured on the same die manufacturing die size. Drawbacks are somewhat low density and performance than other approaches to ASIC design. However this style is often a viable approach for low production volumes.
