<p>Embodiments include systems, methods, and apparatuses to estimate respective first and second cumulative density functions (CDFs) for values of a plurality of non-volatile memory (NVM) cells in a page of memory. The CDFs may be based at least in part on one or more decoder outputs of codewords for data stored in the page. Based at least in part on the CDFs, first and second probability density functions (PDFs) may be estimated for the values of the page of memory. A center read reference voltage may then be determined for reading a cell in the page. The center read reference voltage may be based at least in part on the first and second PDFs.</p> |
