1. A solid state memory system comprising:

  • a first nonvolatile semiconductor (NVS) memory that has a first write cycle lifetime;

    a second nonvolatile semiconductor (NVS) memory that has a second write cycle lifetime that is different than said first write cycle lifetime; and

    a wear leveling module that generates first and second wear levels for said first and second NVS memories based on said first and second write cycle lifetimes and that maps logical addresses to physical addresses of one of said first and second NVS memories based on said first and second wear levels.
