Abstract
A circuit for generating a data strobe signal includes: a control signal generation unit configured to generate a strobe control signal defining an activation time period where a first data strobe signal and a second data strobe signal, which is an inverted signal of the first data strobe signal, are toggled; and a strobe signal output unit configured to output the first and second data strobe signals as a final strobe signal in the activation time period where the strobe control signal is activated.
Claims24
A circuit for generating a data strobe signal, comprising:
- a control signal generation unit configured to generate a strobe control signal defining an activation time period where a first data strobe signal and a second data strobe signal are toggled;
- and
- a strobe signal output unit configured to output the first and second data strobe signals as a final strobe signal in the activation time period where the strobe control signal is activated,
- wherein the second data strobe signal is an inverted signal of the first data strobe signal.
A method for generating a data strobe signal, comprising:
- buffering a first data strobe signal and a second data strobe signal which is an inverted signal of the first data strobe signal;
- generating a strobe control signal defining an activation time period where the first data strobe signal and the second data strobe signal are toggled;
- and
- outputting an output signal of the process of buffering the first data strobe signal and the second data strobe signal as a final strobe signal in the activation time period where the strobe control signal is activated.
A memory system, comprising:
- a memory control device configured to output a data having a termination level corresponding to a power source voltage and a data strobe signal;
- and
- a memory device configured to generate a strobe control signal by buffering a reference voltage having a predetermined voltage level and the data strobe signal, output the data strobe signal as a final strobe signal in an activation time period where the strobe control signal is activated, and synchronize the data in response to the final strobe signal.
