Techniques to truncate data files in nonvolatile memory
View Patent ↗Various embodiments for performing truncate operations in nonvolatile memory are described. In one embodiment, an apparatus may include a nonvolatile memory to perform one or more truncate operations on a data file written to the nonvolatile memory and a volatile memory to track a truncate operation performed in the nonvolatile memory. Other embodiments are described and claimed.
1. An apparatus comprising:
a truncate module, executed by a controller, to perform one or more truncate operations to invalidate a portion of a data file written to a nonvolatile memory; and
said truncate module to track, in a dynamic link table, only a most recent truncate operation performed in said nonvolatile memory in a volatile memory, wherein the dynamic link table is arranged to track only valid information on the data file, wherein said nonvolatile memory to enforce a sequential addressing requirement during the one or more truncate operations.
2. The apparatus of claim 1 , said nonvolatile memory comprising at least one of a NAND flash memory and a NOR flash memory.
3. The apparatus of claim 1 , said volatile memory to track valid data.
4. A system comprising:
a wireless interface comprising an antenna;
a truncate module coupled to said wireless interface, said truncate module to perform one or more truncate operations to invalidate a portion of a data file written to a nonvolatile memory; and
said truncate module to track, in a dynamic link table, only a most recent truncate operation performed in said nonvolatile memory in a volatile memory,
wherein the dynamic link table is arranged to track only valid information on the data file,
wherein said nonvolatile memory to enforce a sequential addressing requirement during the one or more truncate operations.
5. The system of claim 4 , said nonvolatile memory comprising at least one of a NAND flash memory and a NOR flash memory.
6. The system of claim 4 , said volatile memory to track valid data.
7. A method comprising:
performing one or more truncate operations to invalidate a portion of a data file written to a nonvolatile memory; and
tracking, in a dynamic link table, only a most recent truncate operation in a volatile memory,
wherein the dynamic link table is arranged to track only valid information on the data file,
wherein said nonvolatile memory enforces a sequential addressing requirement during the one or more truncate operations.
8. The method of claim 7 , further comprising tracking valid data in the volatile memory.
9. The method of claim 7 , wherein performing a truncate operation comprises writing a truncate object to the nonvolatile memory.
10. The method of claim 7 , wherein tracking a truncate operation comprises tracking a truncate link in the volatile memory.
11. An article comprising a machine-readable storage medium containing instructions that if executed enable a system to:
perform one or more truncate operations to invalidate a portion of a data file written to nonvolatile memory; and
track, in a dynamic link table, only a most recent truncate operation in a volatile memory,
wherein the dynamic link table is arranged to track only valid information on the data file,
wherein said nonvolatile memory enforces a sequential addressing requirement during the one or more truncate operations.
12. The article of claim 11 , further comprising instructions that if executed enable a system to track valid data in the volatile memory.
13. The article of claim 11 , further comprising instructions that if executed enable a system to write a truncate object to the nonvolatile memory.
14. The article of claim 11 , further comprising instructions that if executed enable a system to track a truncate link in the volatile memory.
