Abstract
A method of operating a memory device included in a memory module, includes: receiving, from a memory controller, a unique identification (ID) associated with the memory device; temporarily storing the unique ID in a volatile storage circuit of the memory device; and permanently storing the unique ID in the volatile storage circuit into a non-volatile storage region of the memory device.
Claims20
A method of operating a memory device included in a memory module, the method comprising:
- receiving, from a memory controller, a unique identification (ID) associated with the memory device;
- temporarily storing the unique ID in a volatile storage circuit of the memory device;
- and
- permanently storing the unique ID in the volatile storage circuit into a non-volatile storage region of the memory device.
A memory device comprising:
- a volatile storage circuit configured to temporarily store a unique identification (ID) received from an external controller;
- a non-volatile storage region comprising a set of programmable elements;
- and
- control logic configured to perform a program operation,
- wherein the control logic includes:
- transmitting the unique ID stored in the volatile storage circuit to the non-volatile storage region of the memory device;
- and
- permanently assigning the unique ID to the non-volatile storage region of the memory device.
A method of operating a memory module comprising a plurality of memory devices, the method comprising:
- issuing a command to temporarily store a unique identification (ID) in a register of a target memory device among a set of memory devices;
- performing a verification operation to confirm the unique ID is temporarily stored in the register;
- and
- based on the verification operation, issuing a programming command to permanently program the unique ID, which is resident in the register, into a non-volatile storage region of the target memory device.
