Patent ID: 7991925

Claim:
A method for identifying a device type (DT) of first to N-th devices connected in-series in an interconnection configuration, N being an integer greater than one, a signal propagating through the devices, each of the devices having a memory for data store, a type of the memory being associated with a device type (DT) that is undefined, the method comprising: performing a first propagation by providing a first propagated signal including a binary number to the first device of the interconnection configuration, each of the first to N-th devices incrementing the binary number, an incremented binary number replacing the binary number included in the first propagated signal; recognizing the number of the devices in the interconnection configuration based on the binary number included in the first propagated signal from the interconnection configuration; performing a second propagation by providing a second propagated signal including a search DT and a binary search number (SN) to the first device of the interconnection configuration, each each of the first to N-th devices determining whether the search DT matches the DT associated with the device; modifying the SN included in the second propagated signal in response to a DT match determination result; and recognizing an address of a device associated with the search DT in the interconnection configuration in response to the SN included in the second propagated signal from the N-th device of the interconnection configuration and to the previously recognized number of the devices of the interconnection configuration in response to the first propagated signal.
