Abstract: A memory system may be configured to perform immediate folding of data from a low storage density area to a high storage density area. A low storage density target area may be monitored, and when a capacity of the low storage density target area reaches a threshold level, data stored in the low storage density target area may be folded to an associated high storage density target area. The memory system may utilize a pointer system to manage the folding of data. The pointer system may also be utilized for read operations in order to avoid updating address mapping tables for both the low storage density and the high storage density areas.
