Abstract
An example apparatus for garbage collection can include a memory including a plurality of mixed mode blocks. The example apparatus can include a controller. The controller can be configured to write a first portion of sequential host data to the plurality of mixed mode blocks of the memory in a single level cell (SLC) mode. The controller can be configured to write a second portion of sequential host data to the plurality of mixed mode blocks in an XLC mode. The controller can be configured to write the second portion of sequential host data by performing a garbage collection operation. The garbage collection operation can include adding more blocks to a free block pool than a quantity of blocks that are written to in association with writing the second portion of sequential host data to the plurality of mixed mode blocks.
