Abstract
A switch device includes a phase change switch and a memory for storing a target state of the phase change switch. A controller determines a phase state of the phase change switch, and, if the state of the phase change switch does not correspond to the target state, controls a heater of the phase change switch to change the state of the phase changes switch to the target state.
Claims20
A phase change switch, comprising:
- a phase change material;
- first and second terminals configured to provide a first connection path between the first and second terminals;
- third and fourth terminals configured to provide a second connection path between the third and fourth terminals;
- a heater;
- and
- a fifth terminal configured to provide a control path to the heater,
- the phase change switch having a state corresponding with a resistance of the first connection path and corresponding with a resistance of the second connection path, the first connection path, the second connection path, and the control path being different.

A phase change switch, comprising:
- a phase change material,
- a heater configured to heat the phase change material,
- a first connection path, a resistance of the first connection path corresponding with a state of the phase change material,
- a second connection path, a resistance of the second connection path corresponding with the state of the phase change material, and

A method, comprising:
- providing a phase change switch including:
- a phase change material,
- a heater configured to heat the phase change material,
- first and second terminals,
- a first connection path between the first and second terminals, a resistance of the first connection path corresponding with a state of the phase change material third and fourth terminals,
- a second connection path between the third and fourth terminals, a resistance of the second connection path corresponding with the state of the phase change material, and
- a fifth terminal, the fifth terminal forming a control path for the heater,
- the first connection path, the second connection path, and the control path being different;
- selectively transmitting a signal from the first terminal to the second terminal through the phase change material according to the state of the phase change material;
- and
- controlling the heater of the phase change switch with the control path to change the state of the phase change material.
