This abstract first appeared for US patent application 20250130891 titled 'SEMICONDUCTOR MEMORY DEVICES WITH ERROR CORRECTION
Original Abstract Submitted
a memory system includes a semiconductor memory device and a memory controller to control the semiconductor memory device. the semiconductor memory device includes a memory cell array that is divided into a plurality of sub array blocks arranged in a first direction and a second direction. the memory controller includes an error correction code (ecc) engine. the ecc engine, in a write operation, generates a parity data by performing an ecc encoding on a user data including a plurality of sub data units, generates a main data by interleaving the sub data units based on mapping information such that two sub data units to be stored in one row of a target sub array block are included in one symbol. the mapping information indicates a mapping relationship between the plurality of sub data units and rows of the target sub array block storing the plurality of sub data units.
