Abstract
A flash memory controller with automatic interface mode switching is applied to a flash memory apparatus with a plurality of flash memories and the controller contains: a memory interface, a microprocessor, and an interface mode controller. The microprocessor recognizes the supported interface mode of every flash memory connected with the memory interface in an initial setting process, and individually sets the corresponding interface mode setting value into the interface mode controller. Thus, when the flash memory apparatus is operating in a normal operation state, the interface mode controller can output the corresponding interface mode setting value according to the present enabled flash memory, and the memory interface can adjust and switch the interface mode according to the interface mode setting value outputted by the interface mode controller. Thereby, the present invention can achieve the purpose whereby the flash memory apparatus can speed up accessing and increase efficiency.
