Abstract
An electronic apparatus according an embodiment includes a first memory, a second memory, a gate device, and one or more hardware processors. The first memory stores information. The second memory stores state information indicating whether or not update on the information of the first memory is allowed. The gate device is provided on a bus and controls whether or not to permit access to the second memory based on a control instruction. In a predetermined mode, the one or more hardware processors output, to the gate device, a control instruction to permit access to the second memory, set the state information of the second memory to indicate an updatable state, and update the information of the first memory.
Claims12
An electronic apparatus comprising:
- a first memory configured to store information;
- a second memory configured to store state information indicating whether or not update on the information of the first memory is allowed;
- a gate device provided on a bus and configured to control whether or not to permit access to the second memory based on a control instruction;
- and
- one or more hardware processors configured to
- output, to the gate device, a control instruction to permit access to the second memory corresponding to a predetermined mode,
- set the state information of the second memory to indicate an updatable state, and
- update the information of the first memory.
An electronic apparatus comprising:
- a memory configured to store information;
- and
- one or more hardware processors configured to
- receive an update request for information stored in the memory,
- release a non-updatable state for the memory,
- update the information of the memory, and
- set a non-updatable state for the memory after the information is updated.
A method implemented by a computer, the method comprising:
- storing information in a first memory of the computer;
- storing state information, in a second memory of the computer, indicating whether or not update on the information of the first memory is allowed;
- controlling whether or not to permit access to the second memory based on a control instruction;
- outputting a control instruction to permit access to the second memory corresponding to a predetermined mode;
- setting the state information of the second memory to indicate an updatable state;
- and
- updating the information of the first memory.
A method implemented by a computer, the method comprising:
- receiving an update request for information stored in a memory of the computer;
- releasing a non-updatable state for the memory;
- updating the information of the memory;
- and
- setting a non-updatable state for the memory after the information is updated by the updating.
