Summary:PURPOSE: A flash memory system and an operation controlling method thereof are provided to change the capacity of a flash memory system by attaching or detaching the flash memory. CONSTITUTION: A flash memory chip attaching unit(150) attaches a flash memory(100). A flash controller(200) produces the total storage capacity by adding up the storage capacity of the flash memory attached to the memory chip attaching unit. The flash controller transmits the flash memory ID read command to the memory chip attaching unit. The flash controller determines whether the flash memory is attached or not according to the signal transmitted from a memory chip attaching unit corresponding to the transmitted ID read command. The flash controller successively transmits the ID read command to at least two memory chip attaching units.
