The invention discloses a programmable OTP storage unit and a data protection method thereof, relates to the field of single-
chip computer storage units, solves the problem that the existing OTP
chip is easily damaged by
moisture, comprises an installation outer frame installed inside an electronic device, an
electronic board is fixedly installed on the inner side of the installation outer frame, and the invention cooperates with an air guide mechanism, a lifting mechanism and a transmission mechanism, and can touch a rotating part and a limiting part through a
transmission belt and a fixed disk at the moment when a dehumidifying fan is started, so that the limiting part can no longer limit the connection column, and the OTP storage
chip can move upward under the action of a spring, so that its pins are completely separated from an
integrated circuit base, so as to ensure that the OTP storage chip is not connected to the
electronic board in a humid environment, and avoid the loss of confidential data caused by a
short circuit fault of the OTP storage chip, and at the same time, part of the high-speed
airflow is directly blown to the inside of the
integrated circuit base under the action of an air guide sleeve plate, so as to effectively dehumidify the connection between the OTP storage chip and the
integrated circuit base.
