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.
Claims15
A device, comprising:
- a phase change switch including a phase change material and a heater, the phase change switch comprising first and second terminals configured to provide a first connection path between the first and second terminals, the phase change switch comprising third and fourth terminals configured to provide a second connection path between the third and fourth terminals, 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 phase change switch comprising a fifth terminal configured to provide a control path to the heater, the first connection path, the second connection path, and the control path being different;
- a memory configured to store a target state of the phase change switch;
- and
- a controller configured to determine the state of the phase change switch based on the resistance of the second connection path of the phase change switch, to compare the determined state of the phase change switch with the target state of the phase change switch, and to control the heater of the phase change switch with the control path to change the state of the phase change switch to the target state if the state of the phase change switch does not correspond to the target state.

A method, comprising:
- determining a state of 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,
- third and fourth terminals,
- a second connection path between the third and fourth terminals,

- wherein the state of the phase change switch is determined based on the resistance of the second connection path of the phase change switch;
- comparing the determined state of the phase change switch to a stored target state of the phase change switch;
- and
- changing the state of the phase change switch with the control path to the target state in response to the determined state of the phase change switch not corresponding to the target state of the first connection path.
