Latest Patents

Among his latest patents, one stands out: the "Output pad precharge circuit for semiconductor devices." This invention features an output driver for an integrated circuit that executes a precharge function prior to the availability of internal data, effectively minimizing the access time for that data. The design cleverly separates the pull-up and pull-down circuitry used in this precharge function from the output driver and maintains independence from the data signal level being driven. The circuit includes a sensing mechanism that determines the initial state of the output pad before the output signal is dispatched, thereby identifying whether the voltage level is above or below a specific threshold. Additionally, a control signal generated by a detector indicates when the output is nearing the threshold, guiding the logic to deactivate the precharge circuit when the threshold condition is fulfilled.

Another of his innovative patents is a "Non-volatile integrated circuit having read while write capability using one address register." This advancement involves a non-volatile memory integrated circuit, like a flash memory device built on floating gate transistor technology, enabling read and write operations to occur simultaneously through a single address register. The integrated circuit contains two independent arrays of memory cells, allowing one array to undergo programming or erasing while permitting read operations in the other array. This capability is achieved by bypassing the address register for the read process, showcasing a seamless interaction between multiple memory tasks.
