Fault tolerance for persistent main memory
First Claim
Patent Images
1. A computing system, comprising:
- a processor;
a persistent main memory comprising a fault tolerance capability; and
a memory controller to;
store data in the persistent main memory;
create redundant data;
store the redundant data remotely with respect to the persistent main memory; and
access the redundant data during failure of the persistent main memory.

Abstract
A computing system can include a processor and a persistent main memory including a fault tolerance capability. The computing system can also include a memory controller to store data in the persistent main memory and create redundant data. The memory controller can also store the redundant data remotely with respect to the persistent main memory. The memory controller can further access the redundant data during failure of the persistent main memory.

6. A computing system comprising fault tolerance, the computing system comprising:
-
a persistent main memory for storing data; a remote persistent main memory for storing redundant data; and a memory controller, wherein the memory controller accesses the redundant data when the data in the persistent main memory cannot be accessed. - View Dependent Claims (7, 8, 9, 10, 11, 12)
