Abstract
A termination control circuit for a global input/output line includes a speed determination unit configured to output a termination enable signal which is activated in response to a frequency of an external clock signal and CAS latency information; and a pulse generation unit configured to output a driving signal for driving a termination circuit for the global input/output line in response to a termination control signal and the termination enable signal.
Claims7
A termination control circuit for a global input/output line, comprising:
- a speed determination unit configured to output a termination enable signal which is activated in response to a frequency of an external clock signal and CAS latency information;
- and
- a pulse generation unit configured to output a driving signal for driving a termination circuit for the global input/output line in response to a termination control signal and the termination enable signal.
A termination control method for a global input/output line, comprising:
- determining whether or not a frequency of an external clock signal and CAS latency information satisfy a certain combination in response to receipt of the external clock signal and the CAS latency information;
- and
- outputting a driving signal for driving a termination circuit for a global input/output line when the frequency of the external clock signal and the CAS latency information satisfy the certain combination.
