  • Signal termination scheme for high speed memory modules
    Patent number: 7843213
    Abstract: A memory device is coupled to a subset of lines of a data input/output (I/O) bus. The memory device includes an on-die active termination circuit for terminating the subset of lines of the data I/O bus with a selected impedance being one of a plurality of selectable impedances; a termination value register being coupled to the on-die active termination circuit for storing a value representing the selected impedance; and a termination value setting circuit being coupled to the termination value register, for setting the value representing the selected impedance in the termination value register.
    Type: Grant
    Filed: May 21, 2009
    Date of Patent: November 30, 2010
    Assignee: Nanya Technology Corp.
