Latest Patents

One of Agrawal's latest patents is titled "BIST DDR memory interface circuit and method for testing the same." This invention discloses an apparatus and method for self-testing a DDR memory interface. The built-in-self-test (BIST) memory interface circuit includes a signal multiplier that receives a first clock signal from a tester and outputs a multiplied clock signal. A first multiplexer is utilized to select between a test mode and a normal operating mode, providing an output signal. The circuit also features a delay magnitude generator that receives the multiplied clock signal and provides a second clock signal along with a phase control signal. A series of digitally controlled delay line blocks receive the second clock signal and the phase control signal, outputting a phase-shifted data strobe output signal in response to an internal data strobe input signal. The invention further includes multiplexers for selecting internal data strobe input signals and a phase detector that determines the phase difference between the selected signals, outputting a phase difference value.
