Abstract
Disclosed is a memory system including a controller configured to authenticate a user who inputs a request for discarding the memory system, to verify whether the request is valid when the user is authenticated as a legitimate user, to register discard activation of the memory system when the request is valid, and to transmit the request to a memory device; and the memory device configured to determine whether the transmitted request is valid, and to register the discard activation of the memory system when the request is valid.
Claims15
A memory system comprising:
- a controller configured to authenticate a user who inputs a request for discarding the memory system, to verify whether the request is valid when the user is authenticated as a legitimate user, to register discard activation of the memory system when the request is valid, and to transmit the request to a memory device;
- and
- the memory device configured to determine whether the transmitted request is valid, and to register the discard activation of the memory system when the request is valid,
- wherein the controller is configured to register the discard activation of the memory system by burning at least one electronic fuse, and
- wherein the at least one electronic fuse includes:
- a common electronic fuse indicating whether the memory system is discarded;
- and
- an electronic fuse indicating a method of discarding the memory system.
A method of discarding a memory system, the method comprising:
- authenticating, by a controller, a user who inputs a request for discarding the memory system;
- verifying, by the controller, whether the request is valid when the user is authenticated as a legitimate user;
- registering, by the controller, discard activation of the memory system when the request is valid and transmitting the request to a memory device;
- and
- determining, by the memory device, whether the transmitted request is valid;
- and
- registering, by the memory device, the discard activation of the memory system when the request is valid,
- wherein registering the discard activation of the memory system includes burning at least one electronic fuse, and
- wherein the at least one electronic fuse includes:
- a common electronic fuse indicating discard of the memory system;
- and
- an electronic fuse indicating a method of discarding the memory system.
A method of discarding a memory system including a controller and a memory device, the method comprising:
- receiving, by the controller, a delete command for data of the memory device;
- checking, by the controller, whether the memory device is able to execute the delete command;
- and
- registering discard activation of the memory system when the memory device reaches end of life and is not able to execute the delete command,
- wherein registering the discard activation of the memory system includes burning at least one electronic fuse, and
- wherein the at least one electronic fuse includes:
- a common electronic fuse indicating discard of the memory system;
- and
- an electronic fuse indicating a method of discarding the memory system.
