Systems and methods for acoustic emission monitoring of semiconductor devices

A method for monitoring and identifying states of a semiconductor device, the method comprising:

• sensing acoustic emission emitted by at least one semiconductor device;
• analyzing said acoustic emission;
• and
• providing an output based on said analyzing, said output being indicative at least of whether said at least one semiconductor device is in an abnormal operating state with respect to a normal operating state of said semiconductor device and identifying said abnormal operating state as being a result of malicious interference in said at least one semiconductor device.

A system for monitoring and identifying states of a semiconductor device, the system comprising:

• at least one acoustic sensor operative to sense acoustic emission emitted by at least one semiconductor device, said at least one acoustic sensor being operative to generate at least one output signal based on said sensed acoustic emission;
• and
• a signal processing unit operative to receive said at least one signal from said at least one acoustic sensor and to analyze said at least one output signal,
• said signal processing unit being operative to provide an output based on said analyzing, said output differentiating between read and write operations of said semiconductor device.
