Abstract: Embodiments of decoding data stored in solid-state memory arrays are disclosed. In one embodiment, multiple read operations are performed while taking inter-cell interference (ICI) into account. Soft-decision information, such as log-likelihood ratios (LLRs), is determined by using known data and its corresponding multi-read output. Soft-decision information is provided to a detector. Reliability is improved and performance is increased.
