His innovative work has paved the way for advancements in memory devices, enhancing their efficiency and functionality.
Latest Patents
One of his latest patents is a sensing device for non-volatile memory. This device includes a reference circuit, two switches, a sensing circuit, and a judging circuit. The reference circuit is connected to a first node, while the first switch's control terminal receives an inverted reset pulse. The second switch is connected to the first node and receives a ground voltage at its second terminal. The sensing circuit generates a first sensed current, which is then processed by the judging circuit to produce output data based on this current.
Another notable patent is a sensing circuit and method for multi-level memory cells. This circuit features a cell clock generator, a reference clock generator, a counter, a latching signal generator, a latch, and a count-to-state conversion circuit. The cell clock generator converts a selected memory cell's cell current into a cell clock signal, while the reference clock generator does the same for a reference current. The latching signal generator activates a latching signal when a predetermined count value is reached, allowing the latch to issue a latched count value that determines the storage state of the selected memory cell.
