Claim:
1. An operating method executed by a volatile memory device, the method comprising: performing a first initialization operation for the volatile memory device based on a boot code received from an external memory controller; storing the boot code in an internal register of the volatile memory device; reading the boot code stored in the internal register based on a first signal received from the external memory controller when the first initialization operation causes an operating system (OS) booting error; and performing a second initialization operation for the volatile memory device based on the boot code read from the internal register, wherein: the first initialization operation is a normal boot operation by which the volatile memory device is initialized for a first time after power is applied to the volatile memory device and the external memory controller, and the second initialization operation is a silence boot operation by which the volatile memory device is again initialized while power is continuously supplied to the volatile memory device and the external memory controller after the normal boot operation.
