Abstract
A storage apparatus includes an interface and storage circuitry. The interface communicates with a plurality of memory cells, and an individual one of the plurality of memory cells stores data in multiple programming levels. The storage circuitry configured to program data to a first group of multiple memory cells in a number of programming levels larger than two, using a One-Pass Programming (OPP) scheme that results in a first readout reliability level. After programming the data, the storage circuitry is further configured to read the data from the first group, and program the data read from the first group to a second group of the memory cells, in a number of programming levels larger than two, using a Multi-Pass Programming (MPP) scheme that results in a second readout reliability higher than the first reliability level, and reading the data from the second group of the memory cells.
