20150103593 | Method of Writing Data in Non-Volatile Memory and Non-Volatile Storage Device Using the Same - A method of writing data in a non-volatile memory includes writing data from a first memory unit to a second memory unit of the non-volatile memory; checking a health of the second memory unit to generate a health result; and reserving the data in the first memory unit and mapping information corresponding to the first memory unit when the health result indicates that the second memory unit is unhealthy. | 2015-04-16 |
20150103594 | INTER-CELL INTERFERENCE CANCELLATION - A read module reads memory cells along a first word line by applying a plurality of threshold voltages to the first word line; generates first information about a first memory cell located along the first word line and a first bit line indicating a location of a threshold voltage distribution of the first memory cell relative to the plurality of threshold voltages; reads a second memory cell located along the first word line, a second word line near the first word line, or a second bit line near the first bit line; and generates second information about the second memory cell indicating a state of the second memory cell causing interference to the first memory cell. A compensation module compensates for the interference by assigning one or more of a log-likelihood ratio and a hard decision to the first memory cells based on the first information and the second information. | 2015-04-16 |
