  • Memory interface with adjustable voltage and termination and methods of use
    Patent number: 10613613
    Abstract: A memory interface includes: a pull-up device and a pull-down device, wherein the pull-up device couples between a power rail and a data line, and wherein the pull-down device couples between the data line and ground; and a power supply configured to supply a first power supply voltage to the power rail during a terminated data transmission mode in which a receiving memory interface coupled to the data line has an active on-die termination, and wherein the power supply is further configured to supply a second power supply voltage to the power rail during an unterminated data transmission mode in which the on-die termination does not load the data line, the second power supply voltage being less than the first power supply voltage.
    Type: Grant

  • Systems and methods to provide charge sharing at a transmit buffer circuit
    Patent number: 9698782
    Abstract: A circuit includes a data input in communication with a first transistor stack; a first capacitor having a first capacitance and in communication with a power supply via a first transistor of the first transistor stack, wherein the first transistor is configured to charge the first capacitor in response to the data input receiving a signal corresponding to a first binary value; a data output node coupled between the first transistor stack and a transmission line having a second capacitance; and wherein the first capacitor is coupled between the data output node and a second transistor of the first transistor stack, further wherein the second transistor is configured to discharge the first capacitor to the data output node in response to the data input receiving a signal corresponding to a second binary value.
