  • DEVICE HAVING MULTIPLE CHANNELS WITH CALIBRATION CIRCUIT SHARED BY MULTIPLE CHANNELS
    Publication number: 20170221533
    Abstract: An apparatus includes a first channel, a second channel and a calibration circuit. The first channel includes a first command control circuit. The second channel includes a second command control circuit independent of the first command control circuit. The calibration circuit is shared by the first channel and the second channel to generate a calibration code responsive to a calibration command generated responsive to a first calibration command from the first command control circuit and a second calibration command from the second command control circuit.

  • SEMICONDUCTOR MEMORY DEVICE INCLUDING OUTPUT BUFFER
    Publication number: 20150323971
    Abstract: An apparatus includes an external terminal, an output circuit having an impedance corresponding to a code signal, and a calibration circuit configured to produce the code signal responsive to a comparison of a voltage at the external terminal with a reference voltage, the comparison performed by a first cycle period in a first mode and by a second cycle which is longer than the first cycle period in a second mode.
