Improved Circuit Operations for FinFET Devices (Stephens): Portfolio of Seven U.S. Patents

This cutting-edge portfolio covers technology that facilitates and improves the performance of multi-gate FinFET (Fin Field-Effect Transistor) devices. The invention enables calibration or adjustment of the operation of dual-gate transistors such as those used in a sense amplifier or input receiver configuration, overcoming input offset and related issues. Input offset and transistor behavior matching – particularly at lower voltages and with increasingly smaller device geometrics – can cause inconsistent or incorrect circuit operation. This portfolio directly addresses and solves those potential problems!

Patent No.Description
9,286,955Semiconductor memory device having calibration circuitry for dual-gate transistors associated with a memory array
9,304,525Reference level adjustment for calibration of dual-gate transistors
9,344,080Dual-gate transistor control based on calibration circuitry
9,455,001Semiconductor memory device having calibration circuitry for dual-gate transistors associated with a memory array
9,601,167Semiconductor device having dual-gate transistors and calibration circuitry
9,806,708Reference level adjustment for calibration of dual-gate transistors
9,906,218Dual-gate transistor control based on calibration circuitry

The technology covered by this portfolio enables circuits to be tested from each side (its expected output state) to determine calibration results that can significantly reduce or totally eliminate potential matching problems. Current technology can only test one expected output state, and that limits the level of calibration or correction that is possible. This portfolio’s technology is more detailed so it is far more accurate when correcting offset and/or mismatch problems, important factors in today’s higher-performance, smaller-geometry, lower-voltage operations.

This portfolio would be a critical acquisition that would give the acquirer of the portfolio a patent-protected competitive advantage in high performance applications such as SRAM, NAND and flash devices.

High-Speed, Truly Random Number Generator (Scarlett): U.S. Patent No. 9,971,568 and PCT, European, Chinese and Japanese Patent Applications

There are random acts of kindness, but there is also a need for randomness for many computer applications – from running simulations to encryption to artificial intelligence (AI) applications. The invention covered by this portfolio uses birefringent splitting, a process that is quantum mechanical in nature and known to be unpredictable. A series of layers take a beam of photons and randomly shuffle the energy so that the output is a random light intensity. Pairing this with a pixel detector produces 250 simultaneous streams of 1-2GHz random data.

This portfolio includes U.S. Patent No. 9,971,568 for the "Generation of random numbers through the use of quantum-optical effects within a mirror cavity system" as well as PCT Patent Application 2016141192, European Patent Application 3265906, Chinese Patent Application 107408033 and Japanese Patent Application 2018513506.

There is currently no device that meets the random data requirements of high-performance computers. The device created by this invention will permit its integration into data centers, or it could be scaled down to a chip-level device that can be incorporated into numerous computing solutions. This portfolio provides an opportunity for high-performance super computer manufacturers, chip manufacturers, fiber optics infrastructure providers and hard drive OEMs to provide an added-value service for its customer base.

Grain of Salt Size Chip that Determines Precise Color Wavelength (Raindance): U.S. Patent No. 7,061,610

In the never-ending search for more bandwidth, color multiplexing has become a common practice. Rather than add more fiber optic cable – which means running more conduit – the same fiber optic cable can transmit multiple data streams on different colors. And not just Red, Orange, Yellow, Green, Blue and Violet, but hundreds of colors, each just a slight wavelength different from another color. And it works great just as long as a color does not go slightly off from what it is supposed to be, and network data from a major bank ends up on a call to your mom in Miami.

U.S. Patent No. 7,061,610 for a "Photonic Integrated Circuit Based Planar Wavelength Meter" covers a chip the size of a grain of salt that accurately measures the wavelength of a beam of light. In addition to its usefulness in fiber optic communications monitoring and quality control, it has other applications. It can be used to diagnose an illness by determining the exact color of a drop of blood, for example. It also has consumer applications. The chip can be inserted in a cell phone so your mom can use her cell phone to check the freshness of fruits and vegetables at the market. This patent would be a strategic acquisition for any business in the fiber optics, medical devices or cell phone industries.
