STORAGE CONTROLLER AND STORAGE DEVICE INCLUDING THE SAME

原文（中文）

A storage controller configured to control first to N-th non-volatile memory devices respectively including first to N-th plurality of physical addresses is disclosed. The storage controller may comprise a relocation buffer circuit, a potential collision counter circuit configured to store a plurality of potential collision counts respectively corresponding to a plurality of combinations of the first to N-th plurality of physical addresses, a preliminary relocation circuit configured to store a first relocation candidate data which is stored in a first relocation candidate physical address in the relocation buffer circuit, based on a first plurality of potential collision counts, corresponding to the first relocation candidate physical address, among the plurality of potential collision counts, and a flush circuit configured to flush the first relocation candidate data from the relocation buffer circuit to one of the first to N-th non-volatile memory devices.
