Abstract: A data transfer circuit in a nonvolatile memory device includes first repeaters, second repeaters and signal lines. The signal lines connect the first repeaters and the second repeaters, and include a first group of signal lines and a second group of signal lines alternatingly arranged. The first repeaters include a first group of repeaters activated in a first operation mode and a second group of repeaters activated in a second operation mode. The second repeaters include a third group of repeaters activated in the first operation mode and are connected to the first group of repeaters through the first group of signal lines floated in the second operation mode, and a fourth group of repeaters activated in the second operation mode and are connected to the second group of repeaters through the second group of signal lines floated in the first operation mode.

Abstract: A high resolution impedance adjustment (ZQ) calibration method using a hidden least significant bit (HLSB) is provided. The high resolution ZQ calibration method generates a data input/output (DQ) code of n+1 bits without a calibration time increase by adding the hidden least significant bit (HLSB) to a ZQ code of n bits output in a ZQ calibration operation of an impedance adjustment (ZQ) pad. A change in a termination resistance of the DQ pad is reduced as small as possible by the DQ code of n+1 bits.

Abstract: A strobe signal shaping method for a data storage system includes receiving a strobe signal; boosting a first clock edge portion of the strobe signal when the strobe signal is received after having been idle or paused over a predetermined time period; and returning to an operating mode in which boosting is turned off with respect to a second clock edge portion of the strobe signal.
