1. A method of initializing a storage device in a memory system including a memory controller and the storage device, wherein the storage device includes an interface chip and a plurality of nonvolatile memory devices connected to the interface chip, the method comprising:
- confirming an interface layer depth of the interface chip and at least one nonvolatile memory device among the plurality of nonvolatile memory devices;
resetting the interface chip which connects the plurality of nonvolatile memory devices to the memory controller in response to a reset signal generated by the memory controller; and
then,loading a boot loader from at least one of the plurality of nonvolatile memory devices to the memory controller via the interface chip in response to a nonvolatile memory initialization signal generated by the memory controller; and
initializing the plurality of nonvolatile memory devices by executing the boot loader in the memory controller.

11. A method of initializing a multi-layer storage device in a memory system including a memory controller and the storage device, wherein the storage device includes a first interface chip disposed at a first layer, a second interface chip disposed at a second layer and a plurality of nonvolatile memory devices connected to the second interface chip, the method comprising:
-
resetting the first interface chip disposed at the first layer and the second interface chip disposed at the second layer in response to a reset signal generated by the memory controller; and
then,loading a boot loader via the first and second interface chips to the memory controller from a nonvolatile memory device among the plurality of nonvolatile memory devices which are connected to the second interface chip, in response to a nonvolatile memory initialization signal generated by the memory controller; and initializing the plurality of nonvolatile memory devices by executing the boot loader in the memory controller. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
