Managing Data Reliability

摘要

An apparatus, system, and method are disclosed for managing data reliability. A priority module is configured to receive a storage request for a non-volatile memory device. The storage request may include data associated with a priority. The non-volatile memory device includes a plurality of cells, and each cell encodes a plurality of bits. The bits for a cell provide distinct levels of quality of service. A select module is configured to select a bit for storing the data based on the priority of the data and the level of quality of service of the selected bit. A data management module is configured to manage the data to satisfy a write order for the plurality of bits.

1. A method comprising:
receiving a storage request for a non-volatile recording device, the storage request comprising data having a priority designation, the non-volatile recording device comprising a plurality of cells, each cell comprising a plurality of states and a transition guard band between first and second adjacent states, the plurality of states configured to represent values for a plurality of bits, the transition guard band configured such that bits for a cell provide distinct levels of quality of service; selecting a bit for storing the data based on the priority designation of the data and the level of quality of service of the selected bit; and managing the data to satisfy a write order for the plurality of bits.
