Abstract
Techniques and systems are provided for tracking commands. Such methods and systems can include maintaining a meta page in a volatile memory to track commands. The meta page can comprise information associated with a non-volatile memory superblock. When an invalidation command is received for a first logical address, the first logical address can be stored along with an indication that the data associated with the first logical address is invalid, in a first location in the meta page.
