Abstract
A storage device includes a first physical space including first nonvolatile memory devices, a second physical space including second nonvolatile memory devices physically isolated from the first nonvolatile memory devices, and a storage controller that fetches a command from an external device and performs an operation corresponding to the command in any one of the first and second physical spaces, based on information included in the fetched command.
Claims21
A storage device comprising:
- a first physical space including first nonvolatile memory devices;
- a second physical space including second nonvolatile memory devices physically isolated from the first nonvolatile memory devices;
- and
- a storage controller configured to fetch a command from an external device and perform an operation corresponding to the fetched command in one of the first and second physical spaces, based on information included in the fetched command.
1 more element
An operation method of a storage device, the method comprising:
- fetching by the storage device a command from an external device;
- selecting by the storage device a physical space from among a plurality of physical spaces of the storage device based on information in the command, the plurality of physical spaces being physically isolated from each other and recognized by the external device;
- performing by the storage device an operation corresponding to the command in the selected physical space;
- and
- transmitting by the storage device completion information of the operation corresponding to the command to the external device.
2 more elements
A host device comprising:
- a first core configured to drive a first process;
- a second core configured to drive a second process;
- a host buffer memory including a first submission queue and a second submission queue, wherein the first submission queue is mapped onto a first physical space of an external storage device and queues a first command generated by the first core, and the second submission queue is mapped onto a second physical space of the external storage device physically isolated from the first physical space and queues a second command generated by the second core;
- and
- a host driver configured to provide the first and second commands to the external storage device.
