A motor driver integrated circuit comprises a central processing unit, a memory, and a multiple-time programmable memory. The multiple-time programmable memory is configured to store a motor driver program, the memory has a capacity larger than or equal to a capacity of the multiple-time programmable memory. When the motor driver integrated circuit is powered or reset, the central processing unit copies the driven program from the multiple-time programmable memory to the memory. The motor driver integrated circuit is low in cost. The present invention also provides a motor device having the motor driver integrated circuit.
