Latest Patents

One of his latest patents is titled "Self-convergence of post-erase threshold voltages in a flash memory cell using transient response." This invention provides a method for self-converging erase on a flash memory cell by rapidly switching a bias on a control gate while a lateral field is present in the channel region. The method involves differentially biasing the source and drain of the cell, allowing for a transient response at the floating gate. The net transient vertical field formed across a tunneling oxide facilitates moderate hot carrier injection between the channel region and the floating gate. This self-converging method ensures that carrier injection to the floating gate occurs only when a sufficient number of carriers are removed during the array step. The efficiency of this process minimizes the time required at the end of an erase pulse to achieve the desired response.

Another patent by Feng Frank Qian is also focused on the "Self-convergence of post-erase threshold voltages in a flash memory cell." This patent reiterates the innovative erase method that utilizes rapid bias switching on the control gate while maintaining a lateral field in the channel region. The approach emphasizes the importance of transient responses and the self-converging nature of the method, which enhances the performance of flash memory cells.
