Abstract
A system and method of storing data in a semiconductor-type non-volatile memory is described, where a physical storage address of data is made available to a user application such as a file system and where characteristics of the memory system that may be allocated on a physical or a logical basis to a user are separately characterizable as to performance, size, redundancy, or the like. A read request to the memory system may be serviced by accessing the physical address included in the read request rather than using a logical-to-physical address lookup in the memory system. Garbage collection operations may be performed on a virtual-physical-block basis to preserve the relationship between the physical address known to the user and the actual physical location of the data.
