Latest Patents

One of his latest patents is a memory device and a memory device test system. This invention includes a controller, a multiplexer, a deserializer, a data modifier, a memory cell array, and an error detector. The controller generates signals in response to an address signal and a command signal. The multiplexer outputs a clock signal as internal data signals when the test mode signal is activated. The deserializer deserializes N bit values included in the internal data signals to generate deserialized signals. The data modifier inverts the deserialized signals to generate bit line signals in response to an inversion control signal and the data modifying signals. The memory cell array stores the bit line signals to memory cells corresponding to the address signal. The error detector determines if an error exists in signals read from the memory cells and outputs an error detecting signal.

Another significant patent is related to a data receiver circuit and a method of adaptively controlling equalization coefficients using the same. This invention includes n sampling receivers, n decision feedback equalizer (DFE) circuits, and a data recovery circuit. The n sampling receivers sample an input signal and output n respective sampling signals in response to n respective clock signals. The n DFE circuits equalize the n respective sampling signals in response to a DFE control signal and generate n respective pre-recovery signals. The data recovery circuit selects one of the n respective pre-recovery signals and outputs the selected n pre-recovery signal as a recovered input signal.
