A semiconductor device including a first fin type pattern and a second fin type pattern which protrude from a substrate and are spaced apart from each other to extend in a first direction, a dummy fin type pattern protruding from the substrate between the first fin type pattern and the second fin type pattern, a first gate structure extending in a second direction intersecting with the first direction, on the first fin type pattern, a second gate structure extending in the second direction, on the second fin type pattern, and a capping pattern extending in the second direction, on the first gate structure and the second gate structure, wherein the capping pattern includes a separation part which is in contact with an upper surface of the dummy fin type pattern, and the dummy fin type pattern and the separation part separate the first gate structure and the second gate structure.

Semiconductor device and method for fabricating the same

An error correction apparatus, a method thereof, and a memory device including the apparatus are provided. The error correction apparatus may include: a determination unit configured to determine whether a number of errors in a read word being read and extracted from a multi-level cell (MLC) exists in an error correcting capability range; a read voltage control unit configured to either increase or decrease a read voltage applied to the MLC when the number of errors in the read word is outside the error correcting capability range; and a codeword determination unit configured to analyze a bit error based on the increase or decrease of the read voltage, and to select a codeword corresponding to the analyzed bit error based on a selected read error pattern. Through this, it may be possible to efficiently correct a read error that occurs when the data of the memory device is maintained for a long time.

Apparatus, method and memory device for error correction by increasing or decreasing a read voltage and analyzing frequency information for a read error pattern

Memory devices and/or methods of storing memory data bits are provided. A memory device includes a multi-level cell (MLC) array including a plurality of MLCs, an error correction unit configured to encode data to be recorded in an MLC, where the encoded data is converted to convert the encoded data into a codeword, an error pattern analysis unit configured to analyze a first data pattern included in the codeword corresponding to an error pattern included in the codeword and a data conversion unit configured to convert the analyzed first data pattern into a second data pattern. According to the above memory devices and/or methods, it is possible to efficiently reduce a data error that occurs when the data is stored for a relatively long period of time, thereby improving reliability.
