摘要：Embodiments of the present invention relates to a mapping information

managing apparatus and method for a non-volatile memory supporting different celltypes, and more particularly, to a mapping information managing apparatus and methodfor a non-volatile memory supporting different cell types capable of managing mappinginformation considering physical characteristics of each cell type in the non-volatilememory supporting different cell types in which bits represented by one cell aredifferent from each other. A mapping information managing apparatus (100) for a non-volatile memory (120) supporting different cell types includes: a user request unit (110)used for a user to request a predetermined operation by using a logical address; a non-volatile memory (120) comprising a plurality of memory areas (121, 122) having differentcell types; and a mapping information managing unit (130) storing mapping informationon user data written to a second memory area (122) of the plurality of memory areas in afirst memory area (121).
