Abstract
Memory modules and authorization systems include a nonvolatile memory, an authentication engine configured to receive an initialization request from a user system, configured to generate a certification value based on device identifiers of devices includes in the user system in response to the initialization request and configured to control access to the nonvolatile memory based on the certification value, and a certification value storage configured to store the certification value.
Claims20
A memory module, comprising:
- a nonvolatile memory;
- an authentication engine configured to receive an initialization request from a user system, configured to generate a certification value based on device identifiers of devices included in the user system in response to the initialization request and configured to control access to the nonvolatile memory based on the certification value;
- and
- a certification value storage configured to store the certification value.
An operating method of a memory module including a nonvolatile memory, the operating method comprising:
- receiving an initialization request from a user system;
- selecting one from a secure mode and a normal mode in response to the initialization request;
- receiving device identifiers of devices included in the user system when the secure mode is selected;
- generating a certification value based on the received device identifiers;
- and
- storing the certification value in a certification value storage.
An authorization system, comprising:
- a first user system including at least one first device;
- and
- a memory module accessible by the first user system, wherein the memory module includes,
- at least one nonvolatile memory configured to store data,
- an authentication engine configured to control access to the at least one nonvolatile memory based on a certification value generated based a device identifier received from the at least one first device, and
- a storage configured to store the certification value.
