A memory system, comprising:

• one or more memory devices;
• and
• processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
• receive information indicating a validity of one or more pages of a first block of non-volatile memory cells;
• transfer first data from the first block to a second block of non-volatile memory cells in accordance with the information indicating the validity of the one or more pages, wherein the information indicating that the first data is valid;
• refrain from transferring second data stored to the first block of non-volatile memory cells in accordance with the information indicating the second data is invalid;
• and
• designate the first block as a free block in accordance with transferring the first data and refraining from transferring the second data.

A non-transitory computer-readable medium storing code, the code comprising instructions executable by one or more processors to:

• receive information indicating a validity of one or more pages of a first block of non-volatile memory cells;
• transfer first data from the first block to a second block of non-volatile memory cells in accordance with the information indicating the validity of the one or more pages, wherein the information indicating that the first data is valid;
• remove second data from a second page of the first block in accordance with the information indicating that the second data is invalid;
• and
• designate the first block as a free block in accordance with transferring the first data and removing the second data.
