An exemplary touch controller chip includes a volatile storage device, an interface unit and a control unit. The interface unit is arranged for receiving touch controller firmware outside the touch controller chip, and storing the received touch controller firmware into the volatile storage device. The control unit is arranged for executing the touch controller firmware stored in the volatile storage device to control a touch panel. In addition, an exemplary electronic device includes a touch controller chip and a host, wherein the touch controller chip has no non-volatile storage device used for storing touch controller firmware, and the host is arranged for transmitting the touch controller firmware to the touch controller chip.
