Abstract
A data storage device, in one implementation, includes a memory device having Single Level Cell (SLC) blocks and Multi-Level Cell (MLC) blocks, such as Triple Level Cell (TLC) blocks. If a SLC block is determined to have errors, the SLC block is reallocated as a TLC block. In some implementations, the TLC block is used to store TLC cold data.
