Abstract

This technology relates to a memory control apparatus for processing data into a memory device and an operating method of the memory control apparatus. A method for controlling a memory may include converting received program data with a first address into compressed data, searching a deduplication table including compressed data, a second address of a memory device in which non-compressed data corresponding to the compressed data has been written and a counter indicative of the write number of the data for the converted compressed data, and if the converted compressed data is searched for inthe deduplication table, mapping a second address corresponding to the compressed data in the deduplication table to the first address, not performing a write operation of the memory device for the received program data, and updating the deduplication table.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0124551 filed on September 28, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] Exemplary embodiments of the present invention relate to an apparatus and method of controlling a memory, and more particularly, to an apparatus and method capable of removing double writing of data. Background technique [0004] More recently, the computer environment paradigm has changed to a pervasive computing environment that allows users to access computer systems anywhere, anytime. As a result, the use of portable electronic devices such as mobile phones, digital cameras, laptop computers, etc. has exploded. Portable electronic devices generally employ memory systems that use memory devices to store data. Memory systems, also referred to as data storage devices, can be used as primary or secondary memory devi...
