Abstract: A printed circuit board may include a plurality of printed board assemblies (PBAs) and an interface configured to connect the plurality of PBAs and an external device, wherein the interface includes terminals having an N*M array, and terminals having an N*K array among the terminals having the N*M array are electrically connected to each PBA included in the plurality of PBAs, wherein the each PBA includes a volatile memory, a nonvolatile memory, and at least one processor, and wherein each of the PBAs is configured to: in case that power is supplied from a first terminal among the terminals having the N*K array, transmit a first parameter signal to a second terminal among the terminals having the N*K array; in response to the transmission of the first parameter signal, store boot-loader data received from the external device in the volatile memory; in response to the storing of the boot-loader data, transmit a second parameter signal to a third terminal among the terminals having the N*K array; and in response to the transmission of the second parameter signal, store binary data received from the external device in the nonvolatile memory.
