Abstract
A smart memory module includes at least one memory device connected to at least one channel, a controller configured to control the at least one memory device, and a host interface circuit configured to perform peer-to-peer (P2P) communication with an external device, and to receive, from a host device, a live migration request. The controller is configured to perform, in response to the live migration request, a migration operation of transmitting buffer data to a target device through the P2P communication under a buffer-full condition.
Claims15
A smart memory module comprising:
- at least one memory device connected to at least one channel;
- a controller configured to control the at least one memory device, the controller including a least recently used (LRU) buffer cache configured to store buffer data;
- and
- a host interface circuit configured to perform peer-to-peer (P2P) communication with an external device, and to receive, from a host device, a live migration request,
- the controller configured to perform, in response to the live migration request, a migration operation of transmitting the buffer data to a target device through the P2P communication under a buffer-full condition.
A method of operating a smart memory module, the method comprising:
- performing an initialization operation for live migration from a host device;
- receiving, from the host device, a live migration request;
- and
- performing, in response to the live migration request, a migration operation using a least recently used (LRU) buffer cache,
- the migration operation flushing data stored in the LRU buffer cache to a target device through peer-to-peer (P2P) communication, in response to the LRU buffer cache being full.
