Latest Patents

One of his latest patents is 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. 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 a transistor that includes the charge trapping structure. The parameter set utilized in this method includes only physical parameters, such as layer thickness, band offsets, and dielectric constants.

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 generally in parallel. The trenches contain semiconductor material, such as doped amorphous silicon, which serves as source/drain lines for the memory array. Insulating liners are positioned between the semiconductor material within the trenches and the semiconductor body. A series of word lines overlie the trenches and channel regions, creating an array of cross points. Charge trapping structures are situated between the word lines and channel regions, enabling the storage of data in flash memory cells.
