Patent number: 12626740Abstract: A first-in-first-out (FIFO) storage structure within an integrated-circuit component is loaded with qualification values corresponding to respective pairs of edges expected within a timing strobe signal transmitted to the integrated-circuit component. The qualification values are sequentially output from the FIFO storage structure during respective cycles of the timing strobe signal and a gate signal is either asserted or deasserted during the respective cycles of the timing strobe signal according to the qualification values output from the FIFO storage structure.Type: GrantFiled: July 10, 2024Date of Patent: May 12, 2026Assignee: Rambus Inc.Inventors: Andrew M. Fuller, Robert E. Palmer, Thomas J. Giovannini, Michael D. Bucher, Thoai Thai Le

Patent number: 9419598Abstract: A controllable delay element includes a delay element to provide a variable delay from an input signal to an output signal. The variable delay can be controlled by a digital delay input. The delay element has a delay range that is controlled in response to a delay range input. The delay range of the delay element can be calibrated to a desired range of delays in response to a relative delay between a first timing reference and a second timing reference. A common timing reference is applied to a plurality of receivers and a strobe receiver. The delay through the strobe receiver is adjusted to measure the delay mismatches between the plurality of receivers. The mismatches are used to select a value for the delay through the strobe receiver.Type: GrantFiled: November 12, 2014Date of Patent: August 16, 2016Assignee: Rambus Inc.Inventors: Robert E. Palmer, Michael D. Bucher, Andrew M. Fuller
