摘要
Embodiments of the present invention relates to a mapping information managing apparatus and method for a non-volatile memory supporting different cell types, and more particularly, to a mapping information managing apparatus and method for a non-volatile memory supporting different cell types capable of managing mapping information considering physical characteristics of each cell type in the non-volatile memory supporting different cell types in which bits represented by one cell are different 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 different cell types; and a mapping information managing unit (130) storing mapping information on user data written to a second memory area (122) of the plurality of memory areas in a first memory area (121).
