  • Method and apparatus for supply voltage glitch detection in a monolithic integrated circuit device
    Patent number: 9523722
    Abstract: A monolithic integrated circuit device may include a supply voltage glitch detector for detecting improper supply voltage conditions. Advantageously, the detection threshold of the supply voltage glitch detector is adaptively set based on the mode of operation of the device or a particular part of the device, which is internally known to the device based on certain inputs received by the device, such as commands, interrupts, control signals, and so forth.
    Type: Grant
    Filed: June 2, 2014
    Date of Patent: December 20, 2016
    Assignee: WINBOND ELECTRONICS CORPORATION
    Inventors: Nir Tasher, Valery Teper, Dennis Chin Cheng, Koying Huang
  • Protection against side-channel attacks on non-volatile memory
    Patent number: 9343162
    Abstract: A non-volatile memory (NVM) device includes an NVM array, which is configured to store data, and control logic. The control logic is configured to receive data values for storage in the NVM array, and to write at least some of the received data values to the NVM array and simultaneously to write complements of the at least some of the received data values.
