Simultaneous bi-directional link
First Claim
1. A memory system, comprising:
- a controller;
a memory device; and
a set of signal lines, coupled to the controller and the memory device, for simultaneous communication between the controller and the memory device using a first band of frequencies and between the memory device and the controller using a second band of frequencies, wherein the controller is configured to dynamically adjust the first band of frequencies based on a predetermined data rate between the controller and the memory device and to dynamically adjust the second band of frequencies based on a predetermined data rate between the memory device and the controller.

Abstract
A memory system with a simultaneous bi-directional link includes a controller, a memory device and a set of signal lines coupled to the controller and the memory device. Simultaneous communication between the controller and the memory device on the set of signal lines uses a first band of frequencies, and between the memory device and the controller on the set of signal lines uses a second band of frequencies. The controller is configured to dynamically adjust the first band of frequencies based on a predetermined data rate between the controller and the memory device and to dynamically adjust the second band of frequencies based on a predetermined data rate between the memory device and the controller.
