Abstract
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.
Claims20
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.
An automotive storage controller comprising:
- first registers configured to store a first function including a first physical function;
- second registers configured to store a second function including a second physical function;
- and
- a processor configured to receive a first request corresponding to a first safety integrity level from outside the automotive storage controller having the first safety integrity level, generate a command for performing an operation corresponding to the first request based on the first function based on the first safety integrity level, receive a second request corresponding to a second safety integrity level from outside the automotive storage controller having the second safety integrity level, generate a command for performing an operation corresponding to the second request based on the second function based on the second safety integrity level, and detect generation of errors of the second function while accessing the second registers.
An automotive electronic system comprising:
- a first host processor with a first safety integrity level;
- a second host processor with a second safety integrity level that is higher than the first safety integrity level;
- and
- an automotive storage device configured to perform an operation corresponding to a first request of the first host processor based on a first function including a first physical function in response to the first request, and perform an operation corresponding to a second request of the second host processor based on a second function including a second physical function in response to the second request, wherein the automotive storage device is configured to associate the first physical function with the first host processor based on the first safety integrity level and associate the second physical function with the second host processor based on the second safety integrity level.
