APPARATUS AND METHOD FOR MANAGING PROGRAM OPERATION TIME AND WRITE LATENCY IN MEMORY SYSTEM

摘要

An operation method of a memory system may include monitoring the size of a programmable area included in each of a plurality of open blocks in which a plurality of data having different attributes are stored, respectively, and generating a first free block by performing a first erase operation on a part of a plurality of erase target blocks based on the number of first open blocks, each open block of which the programmable area has a size less than a threshold value, among the plurality of open blocks.
