Reading data from multi-level cell memory |
摘要 |
A method at a data storage device includes determining a first hard bit of a first logical page, the first hard bit corresponding to a particular cell of the MLC memory. A second hard bit of a second logical page is sensed. The second hard bit corresponds to the particular cell. The first hard bit is used as a soft bit of the second logical page to provide reliability information during a decode operation of the second logical page. |

1. A method comprising:
in a data storage device having a multi-level cell (MLC) memory, performing:
determining a first hard bit of a first logical page, the first hard bit corresponding to a particular cell of the MLC memory;sensing a second hard bit of a second logical page, the second hard bit corresponding to the particular cell; andusing the first hard bit as a soft bit of the second logical page to provide reliability information during a decode operation of the second logical page. |
