Claims20
An apparatus, comprising:
- a plurality of driver circuits, each driver circuit of the plurality of driver circuits configured to receive first and second internal strobe signals and receive first and second enable signals, and each driver circuit of the plurality of driver circuits configured to provide a first driver signal based on the first internal strobe signal responsive to an active first enable signal and to provide a second driver signal based on the first internal strobe signal responsive to an active second enable signal, and further configured to provide a third driver signal based on the second internal strobe signal responsive to the active first enable signal and to provide a fourth driver signal based on the second internal strobe signal responsive to the active second enable signal;
- and
- a plurality of data receiver circuits, each data receiver circuit of the plurality of data receiver circuits configured to receive the first, second, third, and fourth driver signals from a respective driver circuit of the plurality of driver circuits and to receive respective data and a data reference voltage, each data receiver circuit of the plurality of data receiver circuits further configured to sample the respective data relative to the data reference voltage having a first voltage with, a first power and to sample the respective data relative to the data reference voltage having a second voltage higher than the first voltage with a second power that is higher than the first power.
An apparatus, comprising:
- a driver circuit configured to:
- receive first and second internal strobe signals and first and second, enable signals,
