Abstract:
One or more embodiments are directed to maintaining versions of data within a solid state memory. At least one request to perform an operation on at least one logical page of a solid state memory is received from a file system. A data structure associated with the at least one logical page is identified. The data structure at least identifies one or more physical pages associated with the at least one logical page, and a version of the at least one logical page represented by a dataset stored in each of the one or more physical page. The operation is performed on the at least one logical page based on the data structure that has been identified.
