In a particular embodiment, a controller is adapted to perform a garbage collection operation to remove redundant data, to predict a performance parameter associated with performance of the garbage collection operation, and to abort the garbage collection operation when the predicted performance parameter exceeds a threshold.

System and method of garbage collection in a memory device

In a particular embodiment, a controller is adapted to control read/write access to a storage media including a pre-allocated area having multiple meta-blocks. The controller includes logic adapted to control the multiple meta-blocks as a first in first out (FIFO) circular queue. The logic selects one or more meta-blocks from the multiple meta-blocks based on an order associated with the FIFO circular queue and selectively writes a logical block address (LBA) mapping table to the selected one or more meta-blocks.

System and method of managing metadata

In a particular embodiment, a controller is disclosed that is adapted to control read/write access to a storage media. The controller includes data corruption detection logic to reconstruct a logical block address (LBA) lookup table from metadata stored at the storage media upon restart and re-initialization after a power loss event. The controller further includes duplicate conflict resolution logic to identify a valid data block from multiple data blocks that refer to a single LBA. The duplicate conflict resolution logic counts a first number of valid physical pages and a second number of different sectors in each of the multiple data blocks. The duplicate conflict resolution logic selects the valid data block from the multiple data blocks based on at least one of the first and second numbers.
