Systems and methods for generating dynamic super blocks

A memory interface for accessing a non-volatile memory, the non-volatile memory comprising a plurality of dies, each die comprising a plurality of physical blocks, the memory interface comprising:

• a bus controller operative to communicate with the non-volatile memory;
• and control circuitry operative to:
• determine that a block of a die of the plurality of dies is not suitable for storing data in a multi-level cell (“MLC”) mode, wherein the determined block is mapped to a first block that requires its data to be stored in the MLC mode;
• and
• remap the determined block from the first block to a dynamic single level cell (“SLC”) super block, wherein the dynamic SLC super block is a block that requires its data to be stored in a SLC mode that has a lower capacity than the MLC mode, and wherein a number of physical blocks mapped to the dynamic SLC super block increases as additional determined blocks are remapped to the dynamic SLC super block.

A method for managing grown bad blocks of a non-volatile memory, the method comprising:

• selecting at least a subset of memory locations of multiple grown bad blocks of the non-volatile memory to form a dynamic super block;
• detecting that the dynamic super block needs to be erased;
• preparing the dynamic super block for reprogramming;
• and
• reconstructing a new dynamic super block from the dynamic super block by progressively increasing the size of the new dynamic super block.
