Systems of semiconductor devices and operating methods thereof

A semiconductor system, comprising:

• a memory storing sequence codes corresponding to a plurality of control programs;
• a peripheral circuit configured to perform a hardware operation in response to control signals output by a processor;
• a sequence controller configured to determine an execution order of the sequence codes;
• and
• a register configured to store the execution order,
• wherein the execution order stored in the register is changeable by an external device after hardware synthesis of the semiconductor system is completed.

A method of operating a semiconductor system, comprising:

• providing a processor, a memory, and a peripheral circuit;
• determining whether a function change request is received from an external device;
• updating, in response to the function change request, at least one of a control program or a sequence processing order of the control program stored in a register;
• and
• controlling the peripheral circuit based on an updated control program or the sequence processing order,
• wherein a function of the semiconductor system is changeable after completion of hardware synthesis by the function change request.

An operating method of a system, wherein the system comprises a processor in communication with a peripheral circuit and a memory device,

• the operating method comprising:
• receiving a request to change a processing order of sequences of a control program from an external device;
• changing the processing order of the sequences;
• and
• executing the control program for the peripheral circuit according to a changed processing order of the sequences,
• wherein a function of the system is changeable after a completion of hardware synthesis of the system by the request.
