Latest Patents
One of her latest patents is titled "Non-volatile memory cell with improved programming technique with decoupling pass gates and equalize transistors." This invention features a four-transistor non-volatile memory (NVM) cell that incorporates a static random access memory (SRAM) cell structure. The NVM cell utilizes a reverse Fowler-Nordheim tunneling programming technique, allowing an entire array to be programmed in one cycle. The use of equalize transistors ensures a more uniform voltage on the floating gates after an erase operation. Additionally, the implementation of decoupling pass gates during a read operation enhances the charge difference on the floating gates of programmed and erased cells.
Another significant patent is "Method of making a non-volatile memory (NVM) cell structure and program biasing techniques for the NVM cell structure." This method involves the formation of multiple NVM cells and an SRAM cell, with specific pass gate structures and equalize structures that respond to various signals. Appropriate biasing conditions are applied to facilitate the programming operations of the NVM cell structure.
