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.
