Abstract
An electronic device is provided. A storage device includes a memory device and a memory controller. The memory device includes a write protection area. The memory controller controls the memory device to perform a read operation on the write protection area, in response to a series of requests regarding security read that are received from a host, provides read data received from the memory device to the host, and generates a device authentication code based on the read data. The memory controller performs generation of the device authentication code in parallel with provision of the read data to the host.
Claims20
A storage device, comprising:
- a memory device including a write protection area;
- and
- a memory controller configured to control the memory device to perform a read operation on the write protection area, in response to a series of requests regarding security read that are received from a host, provide read data received from the memory device to the host, and generate a device authentication code based on the read data,
- wherein the memory controller generates the device authentication code in parallel with providing the read data to the host.
A method of operating a storage device, the method comprising:
- receiving a first request among a series of requests regarding security read and read information from a host;
- reading data stored in a write protection area based on the read information;
- generating a device authentication code based on the read data;
- and
- providing the read data to the host,
- wherein the generating of the device authentication code is performed in parallel with the providing of the read data.
A computing system, comprising:
- a host;
- and
- a storage device, including a write protection area, configured to receive a first request among a series of first and second requests regarding security read and read information from the host, read data stored in the write protection area based on the read information, and provide the read data to the host in parallel with generation of a device authentication code based on the read data.
