Abstract
A system and method for perform inter/intra-memory tiering are provided. The system includes a host CPU; a tier 1 memory; and a memory module including a tier 2 memory and a tier 3 memory. The memory module is configured to perform inter-memory tiering between the tier 1 memory and the memory module, and perform intra-memory tiering between the tier 2 memory and the tier 3 memory.
Claims20
A system for perform inter/intra-memory tiering, the system comprising:
- a host central processing unit (CPU);
- a tier 1 memory;
- and
- a memory module comprising an embedded CPU, a tier 2 memory, and a tier 3 memory,
- wherein the memory module is configured to:
- receive, from the host CPU, an inter-memory tiering configuration,
- receive, from the embedded CPU, an intra-memory tiering configuration,
- perform inter-memory tiering between the tier 1 memory and the memory module, based on the inter-memory tiering configuration, and
- perform intra-memory tiering between the tier 2 memory and the tier 3 memory, based on the intra-memory tiering configuration.
6 more elements
A method of inter/intra-memory tiering by a memory module, the method comprising:
- receiving, from a host central processing unit (CPU), a first configuration for inter-memory tiering between a tier 1 memory and the memory module;
- receiving, from a CPU included in the memory module, a second configuration for intra-memory tiering between a tier 2 memory and a tier 3 memory, the tier 2 memory and the tier 3 memory being included in the memory module;
- tracking page meta of a memory page;
- and
- performing, for the memory page, one of inter-memory tiering between the tier 1 memory and the memory module, or intra-memory tiering between the tier 2 memory and the tier 3 memory, based on the first configuration or the second configuration, respectively, and the tracked page meta.
