| 2002 | Invention patented by Torsten Partsch and George William Alexander on September 24th, 2002. Abstract: A circuit and method for suppressing the effect of noise on a data strobe signal DQS in a double data rate (DDR) SDRAM is provided. The circuit includes a data input latch circuit for receiving data to be stored and for latching the data in a memory array in response to a control signal; and a control signal generator for generating the control signal in response to a data strobe signal wherein the control signal has a predetermined minimum pulse width of the data strobe signal. The control signal generator includes a reset/set flip-flop for generating the control signal, wherein the flip-flop is set by the data strobe signal; and a low pass filter for receiving the data strobe signal and for outputting a reset signal to the flip-flop if the data strobe signal is greater than the predetermined minimum pulse width. |
