Abstract
A memory die executes enhanced foggy-fine program operations to recover foggy programmed data including a distribution that has extended into multiple states. The die includes blocks to store data in various formats. A memory controller on the die receives data from a storage device and generate parity data and enhanced foggy data based on the data received from the storage device. The memory controller stores the parity data and the enhanced foggy data to a cache prior to performing a foggy program operation to a block. The memory controller uses the parity data and the enhanced foggy data to recover the data when a foggy distribution associated with the foggy program operation crosses beyond an adjacent distribution. The memory controller then writes the recovered data to the block with a fine program operation.
