A Clustering-based ML Scheme for Capacity Approaching Soft Level Sensing in 3D TLC NAND

In a 3D TLC solid-state storage system, the LDPC decoding performance is significantly affected by the quality of soft-level sensing. Inspired by the capacity-approaching maximum mutual-information method, this work presents the data-driven approach to collect all the optimal 2-bit soft-read level p…
