Abstract
In a non-volatile memory system that initially writes data in a binary format and then folds the stored data into a multi-level format, transfers of host data from the memory controller to the memory dies of the system are performed during both foggy and fine phases of the multi-level programming as data latches are released, allowing the transfer times to be hidden behind the programming. To improve data throughput one sub-set of the memory dies perform their foggy phase programming while another sub-set of the memory dies perform their fine phase programming, resulting in non-overlapping transfer windows for host data transfers for the two sub-sets of memory dies.
