Abstract
Methods, systems, and devices for wear leveling techniques using data characteristics are described. The described techniques provide for wear leveling across blocks of a memory system. A controller of the memory system may include additional criteria for determining a destination block for an operation, which may include a characteristic of data associated with the operation. The controller may select a destination block according to both an age of the block and the characteristic of the data. For example, the controller may select a relatively young block for data having a first characteristic and may select a relatively old block for data having a second characteristic. In some cases, the controller may partition free blocks into sub-pools based on an average age of virtual blocks (VBs) associated with each free block.
