  • Publication number: 20230030668
    Abstract: A storage device may include: a memory device for extracting bits having a first logic value among bits included in data received from outside the memory device, generating a plurality of compressed data chunks including the bits comprising the first logic value and position information representing positions of the bits having the first logic value in the data, and outputting the plurality of compressed data chunks in response to a data output command; and a memory controller for receiving the plurality of compressed data chunks from the memory device, and recovering the data, based on the bits having the first logic value, which are included in the plurality of compressed data, and the position information.

  • Patent number: 9054697
    Abstract: A majority decision circuit includes: a majority decision unit configured to compare first data with second data to decide whether one of the first data and the second data has more bits with a first logical value; and an offset application unit configured to control the majority decision unit so that the majority decision unit decides, in a case when the number of bits with the first logical value among the first data is equal to the number of bits with the first logical value among the second data, that the first data have more bits with the first logical value if offset is a first setting value in a first phase and decides that the second data have more bits with the first logical value if the offset is a second setting value in a second phase.

  • Patent number: 9018991
    Abstract: A data recovery circuit may include a data sampling unit suitable for sampling source data including an edge data using data clocks and an edge clock, a data extraction unit suitable for extracting the edge data from sampled data outputted from the data sampling unit, a control signal generation unit suitable for generating a phase control signal in response to the edge data, and a multi-clock control unit suitable for controlling phases of the data clocks and the edge clock in response to the phase control signal.
