  • Patent number: 11362093
    Abstract: A method of performing co-integrated fabrication of a non-volatile memory (NVM) and a gate-all-around (GAA) nanosheet field effect transistor (FET) includes recessing fins in a channel region of the NVM and the FET to form source and drain regions adjacent to recessed fins, and removing alternating portions of the recessed fins of the NVM and the FET to form gaps in the recessed fins. A stack of layers that make up an NVM structure are conformally deposited within the gaps of the recessed fins leaving second gaps, smaller than the gaps, and above the recessed fins of the NVM while protecting the FET with the organic planarization layer (OPL) and a block mask. The OPL and block mask are removed from the FET, and another OPL and another block mask protect the NVM while a gate of the FET is formed above the recessed fins and within the gaps.

  • Patent number: 11280112
    Abstract: A dual-unlock combination lock provides a first set of correct password and a second set of correct password to be used independently. After a password switch pushbutton is operated to drive a bracket to a corresponding position, a corresponding correct password is input into a combination wheel, so that an elastic member props the bracket to release from a transmission element in order to unlock the combination lock. One password element can achieve the effect of unlocking the lock by using two sets of correct password independently to provide a broader scope of applicability. The first set of correct password with the setting and use similar to those of a common password is provided for ordinary users, and the second set of correct password is a fixed code provided for designated users to unlock the combination lock by scanning an identification code by a mobile terminal.

  • Patent number: 11270768
    Abstract: A semiconductor structure is provided. The structure includes a RRAM cell having a first end and a second end. The second end is connected to a first potential. The structure includes a decoupling capacitor having a first end connected in series with the first end of the RRAM cell and a second end connected to a second potential. The structure includes a FET arranged across the capacitor to form a bridged capacitor by having a FET source connected to the first end of the capacitor and a FET drain connected to the second end of the capacitor. A paired activation and subsequent deactivation of the FET enables a short protection mode of the capacitor that provides a series resistance above a threshold amount, between the second potential and the first end of the RRAM cell, responsive to a detected short of the capacitor from the supply to the first potential.

  • Publication number: 20220030251
    Abstract: Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In some example implementations, bitstream syntax, semantics of syntax elements and many coding/decoding processes for inter prediction mode are reused or slightly modified to enable intra BC prediction for blocks of a frame. For example, to provide intra BC prediction for a current block of a current picture, a motion compensation process applies a motion vector that indicates a displacement within the current picture, with the current picture being used as a reference picture for the motion compensation process. With this unification of syntax, semantics and coding/decoding processes, various coding/decoding tools designed for inter prediction mode, such as advanced motion vector prediction, merge mode and skip mode, can also be applied when intra BC prediction is used, which simplifies implementation of intra BC prediction.

  • Publication number: 20210376594
    Abstract: The present disclosure discloses a resistive sub-module hybrid MMC and a direct current fault processing strategy thereof. The hybrid MMC prevents fault current from entering a direct current system from the alternating current side by artificially creating three-phase earthing short circuit on the alternating current side of a converter during the direct current fault processing process, and can reduce the number of required power electronic devices compared with the module hybrid MMC. At the same time, the direct current fault processing speed of the hybrid MMC is fast, and the duration of the artificially creating three-phase short circuit fault in the fault processing process is less than 60 ms, which will not have a great impact on the alternating current system. The present disclosure greatly reduces the cost of building an overhead line high-voltage flexible direct current transmission system, and has very strong reference significance and use value in engineering.
