Abstract
On-die-termination control circuit includes a mode detecting unit for detecting a power-down mode and a power-down delay configured to delay an on/off control signal in the power-down mode. On-die-termination control circuit provided a shift register configured to delay an on/off control signal in synchronization with shift clocks in a non-power-down mode, and transfer the on/off control signal as received without delay in a power-down mode, a power-down delay configured to delay the on/off control signal in the power-down mode, and not to delay the on/off control signal in the non-power-down mode and a controller configured to control enabling/disabling of an on-die-termination operation according to information about enable/disable timing of an on-die-termination operation provided by the on/off control signal that have passed through the shift register and the power-down delay.
