    Abstract: A storage device is provided which includes a nonvolatile memory device configured to store a plurality of reference data, a memory configured to store a hash manage table used to manage a plurality of reference hash keys of each of the plurality of reference data, a hash key generator configured to generate a plurality of hash keys based on write requested data, and a memory controller configured to compare the plurality of hash keys and reference hash keys of each reference data to determine whether to store the write requested data in the nonvolatile memory device. The memory controller selects one of the plurality of reference data according to a similarity between the plurality of hash keys and the plurality of reference hash keys of each reference data and stores the write requested data and the selected reference data in the nonvolatile memory device to refer to each other.

    Abstract translation: 提供一种存储装置，其包括被配置为存储多个参考数据的非易失性存储装置，被配置为存储用于管理多个参考数据中的每一个的多个参考散列密钥的散列管理表的存储器，散列密钥 生成器，其被配置为基于写入请求的数据生成多个散列密钥;以及存储器控制器，被配置为比较每个参考数据的多个散列密钥和参考散列密钥，以确定是否将写入请求的数据存储在非易失性存储器件中。 存储器控制器根据多个散列键和每个参考数据的多个参考散列键之间的相似度来选择多个参考数据中的一个，并将写入请求的数据和所选择的参考数据存储在非易失性存储器件中以引用 对彼此。
