Latest Patents

One of his latest patents is titled "Architecture to mitigate configuration memory imprinting in programmable logic." This invention presents a method and architecture for reducing configuration memory imprinting in programmable logic devices. At power-up, a configuration memory inversion control determines whether to operate in normal mode or inversion mode, aiming for equal time in each mode throughout the system's lifecycle. The architecture includes a configuration memory input inversion plane and a configuration memory output inversion plane, which invert data to and from the configuration memory cells. This approach minimizes differences in memory cell stresses, thereby reducing memory imprinting effects.

Another notable patent is "System architecture to mitigate memory imprinting." This invention addresses memory imprinting in electronic system volatile memory. Similar to his previous patent, a bus mode register control determines the operational mode at system power-up. A bi-directional data bus inverter is utilized to invert data from non-volatile memory when copied to volatile memory. This system also aims to balance the time spent by individual memory addresses in high and low voltage states, minimizing memory cell stress and imprinting effects.
