Abstract
A memory device includes a reference voltage generator configured to generate a reference voltage, and a data input/output (I/O) buffer configured to receive a data signal having a first phase, generate a phase control signal having a second phase opposite to the first phase, and generate an output signal based on the data signal, the phase control signal, and the reference voltage.
Claims20
A memory device, comprising:
- a reference voltage generator configured to generate a reference voltage;
- and
- a data input/output (I/O) buffer configured to receive a data signal having a first phase, generate a phase control signal having a second phase opposite to the first phase during a transition of the data signal, and generate an output signal based on the data signal, the phase control signal, and the reference voltage.
A memory system, comprising:
- a memory controller configured to transmit a data signal having a first phase;
- and
- a memory device configured to receive the data signal, and generate an output signal corresponding to the data signal based on a reference voltage for detecting the data signal, a phase control signal having a second phase opposite to the first phase during a transition of the data signal, and the data signal.
A memory device, comprising:
- a reference voltage generator configured to generate a reference voltage;
- and
- a data input/output (I/O) buffer configured to receive the reference voltage through a first node, receive a data signal having a first phase through a third node, generate a phase control signal having a second phase opposite to the first phase during a transition of the data signal, generate an output signal by amplifying a difference between the reference voltage and the data signal, and output the output signal through a second node.
