Abstract
Receiving one or more first write commands to write a first set of data to a storage device. The first set of data is programmed in a plurality of memory cells in the storage device using a first plurality of program levels available in the plurality of memory cells. One or more second write commands to write a second set of data to the storage device is received. The second set of data is programmed in the plurality of memory cells with which the first set of data is programmed. The second set of data is programmed using a second plurality of program levels available in the plurality of memory cells different from the first plurality of program levels. Each program level of the first and second pluralities of program levels is mapped to a respective bit pattern comprising three bits.
