Abstract
In one embodiment of the present invention, a method includes setting an update to data of a memory to a valid status, and changing an original version of the data to a backup status.
Claims11
A method comprising:
- associating a count value with a first modification to a data object, the count value indicative of a valid status;
- and
- thereafter associating the count value with a second modification to the data object.
A machine-readable storage medium containing instructions that, if executed, enable a system to:
- associate a count with a first modification to a data object, the count indicative of a valid status;
- associate the count with a second modification to the data object;
- associate the first modification with a second count indicative of a backup status when the count is associated with the second modification:
- and
- associate the count wit a third modification to the data object and to associate the second modification wit a third count indicative of the backup status.
2 more elements
An apparatus comprising:
- at least one storage device to store code to set an update to data of a memory to a valid status via association of a valid count value therewith and to change an original version of the data to a backup status via association of a second count value therewith in place of the valid count value, wherein the memory comprises a flash memory device;
- and
- a coprocessor within the flash memory device to perform the code.
