1. A wireless communications device, comprising:
- a transceiver;
an interface;
a local memory available to the transceiver, wherein the local memory is not communicably coupled to the transceiver through the interface;
a remote memory communicably coupled to the transceiver through the interface;
a buffer implemented in the local memory; and
a link manager,wherein the link manager is configured to operate the interface in at least an active mode and a power save mode based, at least in part, on a condition of the buffer and a state of the transceiver.

Abstract
Systems and methods are disclosed for operating an interface of an electronic device in an active mode or a power save mode based, at least in part, on a condition of a data exchange module buffer. When buffer space is available, incoming data may be stored locally and the interface used to access remote memory storage may be in a power save mode. The interface may revert to active mode to transfer data to the remote memory, such as after a configurable reception interval. Outgoing data may also be stored in a buffer, allowing the interface to be in a power save mode with information transmitted from the buffer.

37. A non-transitory process-readable storage medium for operating a wireless communications device, wherein the wireless communications device includes a transceiver, an interface, a local memory available to the transceiver, wherein the local memory is not communicably coupled to the transceiver through the interface, a remote memory communicably coupled to the transceiver through the interface, and a buffer implemented in the local memory, the processor-readable storage medium having instructions thereon, when executed by a processor to cause the wireless communications device to:
operate the interface in at least an active mode and a power save mode based, at least in part, on a condition of the buffer and a state of the transceiver. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
