Samsung patents memory module that moves data during live migration

Samsung has filed a patent for a smart memory module that includes a controller with a buffer cache. When a host device requests a live migration, the module sends buffered data to a target device using peer-to-peer communication if the buffer is full.

Why it mattersThis filing describes a specific method for managing data transfer during server or system migrations, which is a routine hardware optimization for data centers.

In the filing’s own words

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.

What exactly they claim (claim 1)

1. 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.
