  • Patent number: 11521051
    Abstract: A neural network computing engine having an array of charge-trap-transistor (CTT) elements which are utilized as analog multipliers with all weight values preprogrammed into each CTT element as a CTT threshold voltage, with multiplicator values received from the neural network inference mode. The CTT elements perform computations of a fully connected (FC) neural network with each CTT element representing a neuron. Row resistors for each row of CTT element sum output currents as partial summation results. Counted pulse generators write weight values under control of a pulse generator controller. A sequential analog fabric (SAF) feeds multiple drain voltages in parallel to the CTT array to enable parallel analog computations of neurons. Partial summation results are read by an analog-to-digital converter (ADC).

  • Publication number: 20220309171
    Abstract: A set of endpoint security events that reflect known security issues is defined and collected. A corresponding set of endpoint security actions to protect the endpoints is defined and implemented. Machine learning is used to build a data model to reflect the relation between endpoint security events and endpoint security actions. The data model is able to predict the security actions directly from the security events, without the intermediate step of determining a threat level. An endpoint application is developed to use the data model directly and apply the security actions whenever security events occur.
