Abstract: In a multi-plane non-volatile memory, good blocks of different planes are linked for parallel operation for storing long host writes. Where bad blocks in one or more planes result in unlinked blocks, the unlinked blocks are configured for individual operation to store short host writes and/or memory system management data. Unlinked blocks may be configured as Single Level Cell (SLC) blocks while linked blocks may be configured as SLC blocks or Multi Level Cell (MLC) blocks.

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.
