On-die termination circuit

摘要

An on-die termination circuit includes: a clock signal generation block configured to output a clock signal in response to a clock enable signal, a termination block configured to perform a termination operation on an input/output pad in response to the clock signal, a first termination control signal, and a second termination control signal, a first termination control block configured to generate the first termination control signal in response to the clock signal and a latency control signal, a second termination control block configured to control a latency of a second command and to generate the second termination control signal in response to the clock signal and the latency control signal, and a clock enable signal generation block configured to generate the clock enable signal in response to the first command, the first termination control signal, and the second command.

1. An on-die termination circuit comprising:
a clock signal generation block configured to output a clock signal during an activation period of a clock enable signal; a termination block configured to perform a termination operation on an input/output pad in response to the clock signal, a first termination control signal, and a second termination control signal; a first termination control block configured to control a latency of a first command and to generate the first termination control signal in response to the clock signal and a latency control signal; a second termination control block configured to control a latency of a second command and to generate the second termination control signal in response to the clock signal and the latency control signal; and a clock enable signal generation block configured to activate the clock enable signal when any one of the first command and the second command is activated.
