Abstract
A memory die estimates a bit-error-rate (BER) for an encoded foggy program operation and uses the BER to determine whether to decode foggy programmed data on the memory die for a fine programming operation. A controller on the die receives data from a storage device and generates parity page(s) based on the data. The controller performs a foggy program operation to write the data to memory cells in a block. The controller separates states in a memory cell into categories based on a value of a parity page associated with a state. The controller also performs soft bit sensing operations and estimates a BER for the memory cell based on the soft bit sensing operations. Based on the BER, the memory controller performs on-die decoding of the foggy programmed data with the parity page(s) or transfers the foggy programmed data to the storage device for decoding.
