Abstract
Storage class memory may be used in an architecture to achieve high performance, high reliability, high compatibility. In some embodiments, reads may be handled in a conventional way used in a memory based model. However writes do not use a memory based model but instead correspond to a storage based model. The hybrid nature can be achieved by setting the storage class memory to be write protected so that all writes must go through a software based block device interface. In some embodiments, the software based block device interface prevents erroneous writes to the storage class memory.
Claims30
A method comprising:
- setting a storage class memory to read only;
- and
- handling writes to said storage class memory using a storage based model with a block device interface.
A non-transitory computer readable medium storing instructions executed by a memory controller to:
- set a storage class memory to read only;
- and
- handle writes to said storage class memory using a storage based model with a block device interface.
An apparatus comprising:
- a storage class memory;
- and
- a processor, coupled to said memory, to seta storage class memory to read only, and handle writes to said storage class memory using a storage based model with a block device interface.
