摘要
A system includes a processor configured to read information from a plurality of memory cells. The processor initiates a first read of raw data from a group of memory cells using a first reference voltage. The processor also initiates a second read of raw data from the group of memory cells using a second reference voltage different from the first reference voltage. The processor further compares the first read to the second read to identify memory cells read with a bit value that changes between the first and second reads. The processor also assigns the memory cells read with a bit value that changes between the first and second reads to a region associated with the second reference voltage. The processor further counts the number of cells read with a bit value that changes to generate a histogram corresponding to soft information for the group of memory cells.
