METHOD AND SYSTEM FOR ONLINE CONVERSION OF BAD BLOCKS FOR IMPROVEMENT OF PERFORMANCE AND LONGEVITY IN A SOLID STATE DRIVE

摘要

One embodiment facilitates data placement. During operation, the system monitors a condition of a plurality of blocks of a non-volatile memory. The system determines that a condition of a first block falls below a first predetermined threshold, wherein the first block has a first capacity. The system formats the first block to obtain a second block which has a second capacity, wherein the second capacity is less than the first capacity.
