UV erasers are specialized devices designed to erase data stored in ultraviolet-erasable programmable read-only memory (EPROM) chips by exposing them to ultraviolet (UV-C) light. These devices play a critical role in electronics manufacturing, chip programming workflows, and hardware debugging. Their importance stems from enabling reusable semiconductor memory solutions in applications ranging from industrial control systems to legacy computer hardware maintenance.
