Title: Da-Guang Yu: Innovator in Memory Circuits
Introduction:
Da-Guang Yu is a distinguished inventor based in Fremont, CA, with a focus on advancements in memory technology. With a total of three patents to his name, his contributions have significantly influenced the efficiency and reliability of non-volatile memory systems.
Latest Patents:
Among his latest patents, Da-Guang Yu developed an innovative method titled “Automatic refresh for improving data retention and endurance characteristics of an embedded non-volatile memory in a standard CMOS logic process.” This method selectively refreshes data in a nonvolatile memory array based on detected failure types via error correction codes. If the page is deemed error-free, the refresh operation is bypassed. Conversely, should single-error words contain erased and programmed bit errors, a refresh operation—which involves an erase and program—will occur. Notably, the erase operation is omitted if the page solely exhibits program failures.
Another significant patent is the “Two bits per cell non-volatile memory architecture.” This invention comprises a memory circuit capable of holding a single binary value, utilizing two bit cells. Each bit cell is designed to store either a logical high or low value. The system ensures that the binary value can be sensed effectively, even without a sense amplifier, depending on which bit cell holds the logical high value.
Career Highlights:
Da-Guang Yu currently works at MoSys, Inc., a company recognized for its innovative memory solutions and semiconductor technologies. His work has played a critical role in addressing challenges in data retention and memory performance.
