Abstract
Official abstract text for this publication.
A method for re-using a soft decoder involves receiving soft data and hard data from memory cells in a memory device, mapping the soft data to a first set of soft information, mapping the hard data to a second set of soft information, and using the soft decoder to decode both the first set and second set of soft information.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: receiving soft data and hard data from memory cells in a memory device; mapping the soft data to a first set of soft information; mapping the hard data to a second set of soft information comprising mapping a bit 0 to +A and mapping a bit 1 to −B; and decoding the first set of soft information and the second set of soft information using a soft decoder, wherein values A and B are chosen by searching over a specified range of value…
