A latency control circuit and method are provided. The latency control circuit includes a DLL circuit, a latency counter circuit, a synchronization circuit, and a delay line circuit. The DLL circuit enters an inactive state after locking the delay time and provides an active signal at a disable state, delay locking information and loop delay information during the inactive state. The synchronization circuit stops providing a first clock signal according to the active signal at the disable state and then synchronously outputs an operation enabling signal and a second clock signal in response to an enablement of the operation signal. The delay line circuit receives the delay locking information, the operation enabling signal, and the second clock signal and outputs an operation delay signal and an output clock signal after the delay time.

Latency control circuit and method

A resistive memory apparatus and a memory cell thereof are provided. The resistive memory cell includes a first transistor, a second transistor, a first resistor and a second resistor. First and second terminals of the first transistor are respectively coupled to a first bit line and a reference voltage. First and second terminals of the second transistor are respectively coupled to a second bit line and the reference voltage. The first resistor is serially coupled on a coupling path between the first terminal of the first transistor and the first bit line, or on a coupling path between the second terminal of the first transistor and the reference voltage. The second resistor is serially coupled on a coupling path between the first terminal of the second transistor coupled and the second bit line, or on a coupling path between the second terminal of the second transistor and the reference voltage.
