Samsung patents storage system that tracks how often data is accessed

Samsung has been granted a patent for a storage system that monitors how frequently specific data is accessed by different software processes. The system uses a controller to track access counts for specific memory addresses and reports this data back to the computing device when requested.

Why it mattersThis technology could help computer systems better manage memory resources by identifying which data is used most often, potentially improving performance for heavy workloads.

In the filing’s own words

Systems and methods for monitoring memory accesses. A storage system comprises a first memory device, a second memory device, and a controller configured to communicate with the first memory device and the second memory device. The controller is configured to: receive, from a computing device, a first request for first data; identify a first address based on the first request; search the first memory device for the first address; modify a first count maintained in the second memory device for the first address; receive from the computing device a second request; and provide the first count in response to the second request.

What exactly they claim (claim 1)

1. A storage system comprising: a first memory device; a second memory device; and a controller configured to communicate with the first memory device and the second memory device, the controller being configured to: receive, from a computing device, a first request for first data, the first request including a first process identifier associated with a first process, wherein the first request is generated according to a compute express link memory (CXL.mem) protocol; identify a first address based on the first request; search the first memory device for the first address; modify a first count in the second memory device for the first address, wherein the first count is stored in association with the first process identifier; receive from the computing device a second request, wherein the second request is generated according to the CXL.mem protocol, the second request includes information of the first address and the first process identifier; and provide the first count based on the information of the first address and the first process identifier.
