Simultaneous bi-directional link

A memory system, comprising:

• a controller;
• a memory device;
• and
• a set of signal lines, coupled to the controller and the memory device, wherein, on each of the signal lines, the controller is to communicate to the memory device using a first band of frequencies while the memory device is communicating to the controller using a second band of frequencies, the set of signal lines including a baseband sub-channel and a passband sub-channel;
• wherein the controller is configured to dynamically adjust each of the first band of frequencies and the second band of frequencies to a value between zero and a maximum band of frequencies based on a predetermined unidirectional data rate that is greater than 1 Gbps, the unidirectional data rate for communicating a unidirectional data streams
• wherein the controller is configured to simultaneously read data from the memory device using the first band of frequencies and write data to the memory device using the second band of frequencies.

A method of communication in a memory system having a controller and a memory device coupled by a set of signal lines, comprising:

• adjusting a first band of frequencies for communicating from the controller to the memory device based on a predetermined data rate from the controller to the memory device;
• adjusting a second band of frequencies for communicating from the memory device to the controller based on a predetermined data rate from the memory device to the controller;
• on each of the signal lines, simultaneously communicating data from the controller to the memory device and from the memory device to the controller;
• and
• simultaneously reading data from the memory device using the first band of frequencies and writing data to the memory device using the second band of frequencies.

A memory system, comprising:

• a control means;
• a memory means;
• and
• a communication means for simultaneously communicating from the control means to the memory means using a first band of frequencies and from the memory means to the control means using a second band of frequencies, wherein the control means includes a configuration means for dynamically adjusting the first band of frequencies based on a predetermined data rate from the control means to the memory means and for dynamically adjusting the second band of frequencies based on a predetermined data rate from the memory means to the control means;
• wherein the control means is configured to simultaneously read data from the memory means using the first band of frequencies and write data to the memory means using the second band of frequencies.
