  • Patent number: 11275966
    Abstract: A calculation method using pixel-channel shuffle convolutional neural network is provided. In the method, an operating system receives original input data. The original input data is pre-processed by a pixel shuffle process to be separated into multiple groups in order to minimize dimension of the data. The multiple groups of data are then processed by a channel shuffle process so as to form multiple groups of new input data selected for convolution operation. The unselected data are abandoned. Therefore, the dimension of the input data can be much effectively minimized. A multiplier-accumulator of the operating system is used to execute convolution operation using a convolution kernel and the multiple new groups of input data. Multiple output data are then produced.

  • Publication number: 20210390997
    Abstract: A method of operating a voltage-controlled magnetic anisotropy (VCMA) magnetic tunnel junction (MTJ) device is disclosed. The MTJ device is switchable between a first resistance state and a second resistance state. A first threshold voltage for switching the MTJ device from the second resistance state to the first resistance state is lower than a second threshold voltage for switching the MTJ device from the first resistance state to the second resistance state. The method includes applying a first voltage pulse across the MTJ device with an amplitude having an absolute value equal to or greater than the first threshold voltage and lower than the second threshold voltage, thereby setting the MTJ device to the first resistance state regardless of whether the MTJ device initially is in the first or second resistance state.
