Abstract
A hierarchical memory system and method. In some embodiments, the method includes: demoting a first page of data from a fast memory to a slow memory; promoting the first page of data from the slow memory to an intermediate memory zone; and promoting the first page of data from the intermediate memory zone to the fast memory, wherein the intermediate memory zone includes a virtual zone within the slow memory.
Claims20
A method, comprising:
- moving a first page of data from a first memory to an intermediate memory zone;
- and
- moving the first page of data from the intermediate memory zone to a second memory based on an access frequency of the first page of data,
- wherein:
- the intermediate memory zone comprises a virtual zone within the first memory.
2 more elements
A system, comprising:
- a processing circuit;
- and
- memory, operatively connected to the processing circuit and storing instructions that, when executed by the processing circuit, cause the system to perform a method, the method comprising:
- moving a first page of data from a first memory to an intermediate memory zone;
- and
- moving the first page of data from the intermediate memory zone to a second memory based on an access frequency of the first page of data,
- wherein:
- the intermediate memory zone comprises a virtual zone within the first memory.
5 more elements
