Solution Approach 1:

The patent replaces the software-based logical erasure process with a physical X-ray irradiation process. Instead of using computer commands to reset bits through logic gates, the invention uses X-ray radiation to physically erase data from non-volatile memory, eliminating the need for software access and device functionality requirements.

Inventive Principle:

Solution Approach 2:

The patent changes the fundamental mechanism of data erasure from electronic/software-based to physical/radiation-based. By controlling X-ray irradiation parameters (power, duration, angle) to match memory types (NAND, NOR, 3D NAND), the system achieves rapid erasure without time-consuming software processes.
