`
`WHAT IS CLAIMED IS:
`
`1.
`
`A system for storing data comprising:
`
`memory space containing volatile memory space and nonvolatile memory space,
`
`wherein the nonvolatile memory space includes both multilevel cell (MLC) space and single
`
`level cell (SLC) space;
`
`at least one controller to operate memory elements and associated memory space;
`
`at least one MLC nonvolatile memory element,
`
`at least one SLC nonvolatile memory element,
`
`at least one random access volatile memory element;
`
`an FTL flash translation layer, wherein the at least one controller, or FTL, or a
`
`10
`
`combination of both maintain an address table in one or more of the memory elements; and
`
`wherein the address table maps logical and physical addresses adaptable to the
`
`system, wherein the mapping is performed as necessitated by the system to maximize
`
`lifetime, and wherein the mapping maps blocks, pages, or bytes of data in either volatile or
`
`nonvolatile, or both, memories.
`
`2.
`
`The system of Claim 1, wherein the memory elements are a module, standalone device, or
`
`multi-chip package.
`
`3.
`
`The system of Claim 1, wherein at least one of the volatile or nonvolatile memories are
`
`embedded in the at least one controller.
`
`4.
`
`5.
`
`6.
`
`The system of Claim 1, wherein the nonvolatile memory is flash memory.
`
`The system of Claim 1, wherein the nonvolatile memory is phase-change memory.
`
`The system of Claim 1, wherein the nonvolatile memory is magnetic random access
`
`memory.
`
`7.
`
`The system of Claim 1, wherein the volatile memory is dynamic random access memory.

`
`PATENT
`
`8.
`
`9.
`
`The system of Claim 1, wherein the volatile memory is static random access memory.
`
`The system of Claim 1, wherein the at least one SLC nonvolatile memory element
`
`includes a hard disk drive (HDD).
