"Memory interface with reduced energy transmit mode" was invented by James Michael O'Connor (Austin, Texas) and Donghyuk Lee (Cedar Park, Texas).
According to the abstract* released by the U.S. Patent & Trademark Office: "PAM encoding techniques that leverage unused idle periods in channels between data transmissions to apply longer but more energy-efficient codes. To improve energy savings, multiple sparse encoding schemes may be utilized selectively to fit different sized gaps in the traffic. These approaches may provide energy reductions, for example with memory READ and WRITE traffic, when transferr...
