Abstract
A memory device may include a memory cell array, a register group and a logic controller. The register group may include a plurality of registers configured to store set values used for various operations on the memory cell array, and a specific register including a first address information of at least one accessible register selected from the plurality of registers. The logic controller may compare second address information and the first address information, and allow or block access of the accessible register based on the comparison result. The second address is received with a register access command from an external device.
Claims18
A memory device comprising:
- a memory cell array;
- a register group including a plurality of registers configured to store set values used for operations of the memory cell array, the plurality of registers comprising a specific register including first address information of at least one accessible register selected from the plurality of registers;
- and
- a logic controller configured to compare second address information to the first address information, and to allow or block access of the accessible register based on the comparison result,
- wherein the second address information is input with a register access command from an external device.
A method of operating a memory device, the method comprising:
- reading set values used for operations of the memory device from a memory cell array and storing the set values in a plurality of registers;
- storing first address information of at least one accessible register of the plurality of registers in a specific register;
- comparing the first address information with second address information when a register access command and the second address information are received from an external device;
- and
- allowing or blocking access of the accessible register based on the comparison result.
A memory device comprising:
- a register group including a plurality of registers configured to store set values used for operations of the memory device, and a specific register including first address information of at least one accessible register of the plurality of registers;
- and
- a logic controller configured to compare the first address information with second address information, and to allow access of the accessible register, when the first address information matches the second address information,
- wherein the second address information is input with a register access command provided from an external device.
