Abstract
A method for performing detection control of a write protection function of a memory device, an associated control chip, and an associated electronic device are provided. The method includes: detecting whether the memory device supports a first protocol to generate an interface detection result; detecting whether a write protection switch of the memory device is turned on to generate a write protection detection result; and according to the interface detection result and the write protection detection result, selectively initializing a transmission interface of a control chip as a first transmission interface conforming to the first protocol or a second transmission interface, to allow a host device to access the memory device through the control chip, wherein the first transmission interface corresponds to a first configuration of the control chip, and the second transmission interface corresponds to a second configuration of the control chip.
