Abstract
A storage device may use unused bits in a memory device communicatively coupled to the storage device to reduce resource usage and time on the storage device during background operations. The memory device includes a plane having a redundant column section including unused bits. When the storage device receives instructions from a host device, a controller on the storage device may determine that the instructions are associated with data to be discarded from the memory device and may associate the data to be discarded with fragments in the memory device. The controller may generate relocation information, associate the relocation information with data stored in the memory device, and store the relocation information in the unused bits. During relocation operations, the controller may use the relocation information to determine whether fragments in the memory device include the data to be discarded and/or whether to move data in the memory device.
