Abstract
A memory device includes a memory array configured to store data, and a peripheral circuit coupled to the memory array and including a control logic circuit to control operations of the peripheral circuit. The control logic circuit includes a main control circuit and at least one first sub control circuit, and the main control circuit and the first sub control circuit interact through a first trigger signal and a first indication signal. The main control circuit and the first sub control circuit interact through an asynchronous control logic without a global clock signal.

A memory device, comprising:
- a memory array configured to store data;
- and
- a peripheral circuit coupled to the memory array and comprising a control logic circuit to control operations of the peripheral circuit,
- wherein the control logic circuit comprises a main control circuit and at least one first sub control circuit, and the main control circuit and the first sub control circuit interact through a first trigger signal and a first indication signal.
A control logic circuit for control operations of a peripheral circuit of a memory device, comprising:
- a main control circuit and at least one first sub control circuit interacting each other through a first trigger signal and a first indication signal,
- wherein the sub control circuit comprises:
- an asynchronous control circuit configured to receive the first trigger signal and generate a local clock signal;
- and
- a state machine circuit configured to receive the local clock signal and generate the first indication signal.
A method of operating a peripheral circuit of a memory device, comprising:
- generating a trigger signal by a main control circuit;
- receiving the trigger signal by a sub control circuit;
- generating a local clock signal in the sub control circuit;
- triggering a state machine circuit in the sub control circuit by the local clock signal;
- and
- generating an indication signal by the sub control circuit and transmitting the indication signal to the main control circuit.
