摘要:
Embodiments of the present invention include dense, but assessible and well-interconnected component arrangements within multi-component systems, such as high-end multi-processor computer systems, and methods for constructing such arrangements. In a described embodiment, integrated-circuit-containing processing components, referred to as a 'flat components' (202, 206), are arranged into local blocks (400) of intercommunicating flat components. The local flat-component blocks are arranged into interconnected, primitive multi-block repeating units (700), and the primitive local-block repeating units are layered togehter in a three-dimensional, regularly repeating structure that can be assembled to approximately fill any specified three-dimensional volume (Figure 9). The arrangement provides for relatively short, direct pathways (1312-1320) from the surface of the specificed volume to any particular local block component within the three-dimensional arrangement.

An apparatus (100) for controlling propagation of incident electromagnetic radiation (110) is described, comprising a composite material (102) having electromagnetically reactive cells (106) of small dimension relative to a wavelength of the incident electromagnetic radiation (110). At least one of a capacitive and inductive property of at least one of the electromagnetically reactive cells (106) is temporally controllable to allow temporal control of an associated effective refactive index encountered by the incident electromagnetic radiation (110) while propagating through the composite material (106).

Various embodiments of the present invention are directed to electronic means for reading the content of a nanowire-crossbar memory. In one embodiment of the present invention, a microscale or sub-microscale signal line (402) is interconnected with one set of parallel nanowires (310-315) emanating from a nanowire-crossbar memory by configurable, nanowire-junction switches (404). The microscale or sub-microscale signal line (402) serves as a single-wire multiplexer, allowing the contents of any particular single-bit atorage element (316) within the nanowire-crossbar memory to be read.
摘要:
In various embodiments of the present invention, tunable resistors (1102) are introduced at the interconnect layer of the integrated circuits (102) in order to provide a means for adjusting internal voltage and/or current levels within the integrated circuit to repair defective components or to configure the integrated circuit following manufacture. For example, when certain internal components, such as transistors, do not have specified electronics characteristics due to manufacturing defects, adjustment of the variable resistances of the tunable resistors (1102) included in the interconnect layer of integrated circuits according to embodiments of the present invention can be used to adjust internal voltage and/or levels in order to ameliorate the defective components. In other cases, the tunable resistors may be used as switches to configure integrated circuit components, including individual transistors and logic gates as well as larger, hierarchically structured functional modules and domains. In some cases, components and modules may be turned off, while, in other cases, components and modules may be turned on.

Various embodiments of the present invention include three-dimensional, at least partially nanoscale, electronic circuits and devices in which signals can be routed (1016) in three independent directions, and in which electronic components can be fabricated at junctions (510, 802) interconnected by internal signal lines ( 502-509 and 702-709). The three-dimensional, at least partially nanoscale, electronic circuits and devices include layers, the nanowire or microscale-or-submicroscale/nanowire junctions of each of which may be economically and efficiently fabricated as one type of electronic component. Various embodiments of the present invention include nanoscale memories, nanoscale programmable arrays, nanoscale multiplexers and demultiplexers, and an almost limitless number of specialized nanoscale circuits and nanoscale electronic components.

One embodiment of the present invention provides a demultiplexer implemented as a nonowire crossbar (3000) or a hybrid nanowire/microscale-signal-line crossbar with resistor-like nanowire junctions. The demultiplexer of one embodiment provides demultiplexing of signals input on k microscale address lines (3003, 3004) to 2k or fewer nanowires (3006-3009), employing supplemental, internal address lines (3010, 3012) to map 2k nanowire addresses to a larger, internal, n-bit address space, where n > k. A second demultiplexer embodiment of the present invention provides demultiplexing of signals input on n microscale address lines to 2k nanowires, with n > k, using 2k, well-distributed, n-bit external addresses to access the 2k nanowires. Additional embodiments of the present invention include a method for evaluating different mappings of nanowire address to internal address-spaces of different sizes, or to evaluate mappings of nanowires to external address-spaces of different sizes, metrics for evaluating address mapping and demultiplexer designs, and demultiplexer design methods.
