Abstract
Broadly speaking, embodiments of the present technique provide apparatus and methods for improved wear-levelling in (volatile and non-volatile) memories. In particular, the present wear-levelling techniques comprise moving static memory states within a memory, in order to substantially balance writes across all locations within the memory.
Claims28
A method of wear-levelling, the method comprising:
- identifying, within a storage system, a memory location storing static memory states;
- identifying a free memory location in a write heavy region within a memory of the storage system;
- and
- writing the stored static memory states to the free memory location in the write heavy region within the memory.

A non-transitory storage medium to comprise processor-readable instructions stored thereon which are executable by a processor to cause the processor to:
- identify, within a storage system, a memory location storing static memory states;
- identify a free memory location in a write heavy region within a memory of the storage system;
- and
- write the stored static memory states to the free memory location in the write heavy region within the memory.
A storage system comprising:
- a memory;
- and
- one or more processors coupled to the memory to:
- identify, within the storage system, a memory location storing static memory states;
- identify a free memory location in a write heavy region within the memory;
- and
- write the stored static memory states to the free memory location in the write heavy region within the memory.
