Abstract
A memory expanding device for expanding a main memory of an external device connected to the memory expanding device through an optical interface.
Claims20
A memory expanding device, comprising:
- an optical interface that transfers an optical signal between the memory expanding device and an external device connected to the memory expanding device through the optical interface;
- a memory that stores data;
- and
- a control unit that expands a main memory of the external device to include the main memory and the memory of the memory expanding deice in response to receiving a memory expansion instruction in the optical signal from the external device through the optical interface.

A handheld mobile device, comprising:
- a processor;
- a main memory;
- an optical interface that transfers an optical signal between the handheld mobile device and a memory expanding device connected to the handheld mobile device through the optical interface;
- and
- a controller that transmits to the memory expanding device a memory expansion instruction in the optical signal through the optical interface to expand the main memory of the handheld mobile device to include a memory of the memory expanding device, in response to a command of the processor, wherein the processor controls the memory expanding device to expand the main memory of the handheld mobile device to include the main memory and the memory of the memory expanding device.

9 more elements
A method of expanding memory of a host device, the method comprising:
- executing, by a processor of the host device, an application;
- determining that a main memory of the host device is insufficient to complete execution of the application;
- detecting that a memory of a memory expanding device connected to the host device through an optical input of the host device is available to the host device;
- establishing a connection with the memory expanding device to enable expansion of memory available to the host device;
- expanding the memory available to the host device to include the main memory and the memory of the memory expanding device;
- and
- executing the application using the expanded memory available to the host device.
