摘要: A glass optical reflective tap is described that optically connects two optical fibers and may tap a portion of the light that is being communicated between the optical fibers. In one embodiment of the invention, the optical filter includes two D-lenses that operate as focusing or collimator lenses. The first D-lens focuses an optical signal onto a tap filter that allows a majority of the light within an optical signal to pass and also reflects a small portion of optical signal light to a reflective port. The second D-lens focuses the passed light into a transmission port of an optical fiber.

摘要: A package for maintaining alignment of components includes a frame and a beam with the beam attached to the frame and one end of the beam. One or more components are mounted to the beam. The frame and a portion of the beam are separated from each other by a channel which allows portions of the beam to flex substantially independently of the frame when a force is applied to the frame. Thus, the effects resulting from forces applied to the frame are not experienced by the beam, or are at least attenuated, so that the alignment of the components mounted on the beam is substantially preserved.

摘要: A memory and method for accessing data in a memory which uses non redundant-form address decoders is disclosed. Lines in subarrays of the memory are selected using the redundant-form addresses. The least significant bit of the non redundant-form address is used to select between these lines. The compare function of the cache memory is then done with a non redundant-form address.

摘要: In some embodiments, the invention includes an integrated circuit including a bitline and a bitline#, wordlines, and memory cells. The memory cells each corresponding to one of the wordlines and each include first and second pass transistors coupled between first and second storage nodes, respectively, and the bitline and bitline#, respectively, the corresponding wordline being coupled to gates of the first and second pass transistors. The memory cells include first and second inverters cross-coupled between the first and second storage nodes, wherein the first and second pass transistors each have a lower threshold voltage than do transistors of the first and second inverters. Wordline voltage control circuitry coupled to the wordlines selectively controls wordline signals on the wordlines. In some embodiments, the wordline voltage control circuitry asserts the wordline signal for a selected wordline corresponding to a memory cell selected to be read and underdrives the wordline signals for the wordlines not corresponding to the selected memory cell.

摘要: Techniques and circuitry are disclosed for efficiently implementing programmable memory array circuit architectures, such as PROM, OTPROM, and other such programmable non-volatile memories. The circuitry employs an antifuse scheme that includes an array of memory bitcells, each containing a program device and an antifuse element configured with current path isolation well and for storing the memory cell state. The bitcell configuration, which can be used in conjunction with column/row select circuitry, power selector circuitry, and/or readout circuitry, allows for high-density memory array circuit designs and layouts.
