Abstract
Systems and methods for managing content in a flash memory. Data structures such as trees and graphs are implemented in a flash memory. Nodes or field nodes such as pointers or invalidation bits are updated using an overwrite operation where possible or by invalidating certain fields and temporarily storing changes in an in-memory table.
