Memory module for performing one-time programmable (otp) addressing operation to store unique id of each memory device in an id storge region of each memory device, and storage device including the same

Abstract

A method of operating a memory module that communicates with a memory controller includes: entering a one-time programmable (OTP) addressing mode based on an OTP command received from the memory controller; determining whether a guard key sequence is satisfied based on a plurality of mode register commands received from the memory controller; and programming, based on a determination that the guard key sequence is satisfied, a unique identifier (ID), corresponding to a target memory device, into the target memory device, among a plurality of memory devices included in the memory module.
