Latest Patents

Wu's latest patents include a design tool for charge trapping memory using simulated programming operations. This innovative method simulates the operation of a charge trapping memory cell by computing the amount of charge trapped through various tunneling currents. It determines the first tunneling current through the tunneling layer, the second tunneling current out of the charge trapping layer to the gate, and the third tunneling current escaping from traps in the charge trapping layer. The integration of these tunneling currents over a time interval allows for the computation of a change in threshold voltage for transistors that include the charge trapping structure.

Another notable patent involves flash memory that features insulating liners between source/drain lines and channels. This memory array consists of a semiconductor body with multiple trenches aligned in parallel, containing semiconductor material that acts as source/drain lines. The insulating liners separate the semiconductor material within the trenches from the semiconductor body. Additionally, a plurality of word lines overlies the trenches and channel regions, creating an array of cross points. The charge trapping structures between the word lines and channel regions are designed to be programmed and erased, enabling data storage.
