Latest Patents

Among Ji-Ho Cho's most recent innovations is the patent for a nonvolatile memory device and its program method. This advanced program method involves a plurality of programming loops designed to enhance memory efficiency. Notably, at least one loop divides the channel of a selected cell string into a first side channel and a second side channel across two intervals. During the first interval, the method entails turning off the string selection transistor by applying a voltage at a first level, while simultaneously boosting the voltages in the side channels. The second interval sees a change in strategy, applying a different voltage to activate the string selection transistor, which allows for the execution of a hot carrier injection (HCI) program operation. This innovative approach significantly optimizes the programming process of memory cells.
