Latest Patents

One of his latest patents is titled "Apparatus and method for preventing error in physically unclonable function." This invention addresses the issue of bit errors in static random access memory (SRAM)-based Physically Unclonable Functions (PUFs). The method involves selecting an input value from a PUF based on a volatile memory device and checking the corresponding response. It classifies cells based on the frequency of error occurrence and calculates the number of "white cells" where errors do not occur. This process helps determine whether the number of white cells exceeds a preset threshold, allowing for improved reliability in PUF applications.

Another notable patent is the "Method and apparatus for controlling operation of flash memory." This invention provides a control unit and a voltage adjustment unit that work together to manage the operation of flash memory. The control unit outputs a signal to change the program, erase, and read voltage conditions based on a PUF mode selection signal. The voltage adjustment unit then modifies these conditions accordingly, enhancing the performance and adaptability of flash memory systems.
