摘要： An optical modulator includes a ring resonator with a waveguide adjacent to and optically coupled to the micro-ring resonator. A p-i-n junction is formed about the ring resonator. An optional additional doped region may be formed opposite the waveguide from the ring resonator and when combined with the p-i-n junction forms a nearly closed p-i-n junction about the ring resonator. The ring resonator may be a silicon micro-ring resonator. Multiple different resonant frequency resonators may be coupled to the waveguide along with different detectors to multiplex light on the waveguide. The spectrum of the resonator may be controlled by an applied voltage. A prepulsing device may be used to enhance electrical transitions to enhance the speed of the modulator.

摘要： The present disclosure is directed to systems and methods of implementing a neural network using in-memory, bit-serial, mathematical operations performed by a pipelined SRAM architecture (bit-serial PISA) circuitry disposed in on-chip processor memory circuitry. The on-chip processor memory circuitry may include processor last level cache (LLC) circuitry. The bit-serial PISA circuitry is coupled to PISA memory circuitry via a relatively high-bandwidth connection to beneficially facilitate the storage and retrieval of layer weights by the bit-serial PISA circuitry during execution. Direct memory access (DMA) circuitry transfers the neural network model and input data from system memory to the bit-serial PISA memory and also transfers output data from the PISA memory circuitry to system memory circuitry. Thus, the systems and methods described herein beneficially leverage the on-chip processor memory circuitry to perform a relatively large number of vector/tensor calculations without burdening the processor circuitry.

摘要： An embodiment of the invention includes a memory cell having a magnet layer coupled to a metal layer and read line. The metal layer is also coupled to write and sense lines. During a write operation charge current is supplied to the metal layer via the write line and induces spin current and a magnetic state within the magnet layer based on the spin Hall effect. During a read operation read current is supplied, via the read line, to the magnet layer and then the metal layer and induces another spin current, within the metal layer, that generates an electric field and voltage, based on inverse spin Hall effect, at a sense node coupled to the sense line. The voltage polarity is based on the aforementioned magnetic state. The memory operates with a low supply voltage to drive charge, read, and spin currents. Other embodiments are described herein.

摘要： An optical switch structure and a method for fabricating the optical switch structure provide at least two ring waveguides located and formed supported over a substrate. At least one of the at least two ring waveguides includes at least one PIN diode integral with the ring waveguide as a tuning component for an optical switch device that derives from the optical switch structure. The PIN diode includes different doped silicon slab regions internal to and external to the ring waveguide, and an intrinsic region there between that includes the ring waveguide. The method uses two photolithographic process steps, and also preferably a silicon-on-insulator substrate, to provide the ring waveguides formed of a monocrystalline silicon semiconductor material.
