Samsung patents car memory that separates safety-critical tasks from basic ones

Patent drawing from the official filing.

Samsung has been granted a patent for a storage device designed specifically for cars. It uses a controller to route data requests from different car systems to separate physical parts of the memory based on how critical each system is to safety.

Why it mattersThis could help ensure that essential safety functions in a vehicle remain stable and reliable, even when other non-critical systems are using the same storage hardware.

In the filing’s own words

An automotive storage device includes: a nonvolatile memory device configured to store data; and a storage controller configured to receive a first request from a first host, control the nonvolatile memory device so that the nonvolatile memory device performs an operation corresponding to the first request by using a first function including a first physical function, receive a second request from a second host having a safety integrity level that is different from that of the first host, and control the nonvolatile memory device so that the nonvolatile memory device performs an operation corresponding to the second request by using a second function including a second physical function.

What exactly they claim (claim 1)

1. An automotive storage device comprising: a nonvolatile memory device configured to store data; and a storage controller configured to receive a first request from a first host having a first safety integrity level, control the nonvolatile memory device so that the nonvolatile memory device performs an operation corresponding to the first request by using a first function including a first physical function associated with the first host based on the first safety integrity level, receive a second request from a second host having a second safety integrity level that is different from the first safety integrity level, and control the nonvolatile memory device so that the nonvolatile memory device performs an operation corresponding to the second request by using a second function including a second physical function associated with the second host based on the second safety integrity level.
