摘要:
Example embodiments may provide a memory device and memory data reading method. The memory device according to example embodiments may include a multi-bit cell array, an error detector which may read a first data page from a memory page in the multi-bit cell array and may detect an error-bit of the first data page, and an estimator which may identify a multi-bit cell where the error-bit is stored and may estimate data stored in the identified multi-bit cell among data of a second data page. Therefore, the memory device and memory data reading method may have an effect of reducing an error when reading data stored in the multi-bit cell and monitoring a state of the multi-bit cell without additional overhead.

A memory system includes: a memory controller including an error correction decoder. The error correction decoder includes: a demultiplexer adapted to receive data and demultiplex the data into a first set of data and a second set of data; first and second buffer memories for storing the first and second sets of data, respectively; an error detector; an error corrector; and a multiplexer adapted to multiplex the first set of data and the second set of data and to provide the multiplexed data to the error corrector. While the error corrector corrects errors in the first set of data, the error detector detects errors in the second set of data stored in the second buffer memory.
