Title: Chee T Chua: Innovator in Non-Volatile Memory Technology
Introduction
Chee T Chua is a notable inventor based in Fremont, CA, specializing in advancements in non-volatile memory technology. With a total of 2 patents, he has made significant contributions to the field, particularly in improving data retention and endurance characteristics of memory systems.
Latest Patents
One of his latest patents is titled "Automatic refresh for improving data retention and endurance characteristics of an embedded non-volatile memory in a standard CMOS logic process." This invention presents a method for selectively refreshing data in a nonvolatile memory array based on failure types detected by an error correction code. If the page is determined to be error-free, no refresh operation takes place. However, if single-error words on a page contain erased and programmed bit errors, a refresh operation, consisting of an erase and program, is executed. The erase operation is skipped if single-error words solely contain a program failure.
Another significant patent is "Two bits per cell non-volatile memory architecture." This invention describes a memory circuit designed to hold a single binary value. A first bit cell holds either a logical high or low value, while a second bit cell also holds one of these values. Circuitry is provided to place a logical high value in the first bit cell when the binary value is to be high, and similarly for the second bit cell when the value is low. This design allows the memory circuit to be sensed without the use of a sense amplifier.
