A device includes an electrode structure including conductive patterns sequentially stacked on a substrate, a semiconductor pattern penetrating the electrode structure and including channel regions adjacent to the conductive patterns and vertical adjacent regions between the channel regions, and a semiconductor connecting layer extending from an outer sidewall of the semiconductor pattern to connect the semiconductor pattern to the substrate.
Abstract:
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.

Abstract:
A semiconductor memory device includes a stack of word lines and insulating patterns. Cell pillars extend vertically through the stack of word lines and insulating patterns with memory cells being formed at the junctions of the cell pillars and the word lines. A ratio of the thickness of the word lines to the thickness of immediately neighboring insulating patterns is different at different locations along one or more of the cell pillars. Related methods of manufacturing and systems are also disclosed.
