Abstract
In a non-volatile memory storage system such as a flash EEPROM system, a controller switches the manner in which data sectors are mapped into blocks and metablocks of the memory in response to host programming and controller data consolidation patterns, in order to improve performance and reduce wear. Data are programmed into the memory with different degrees of parallelism.
