Apparatus and method for producing ids for interconnected devices of mixed type

A method for assigning a device identifier at a first device coupled to a second device in a serial interconnection configuration, the first device having a serial input connection coupled to a serial output connection of a previous device in the serial interconnection configuration, the second device having a serial input connection coupled to a serial output connection of the first device, the method comprising:

• receiving a device identifier (ID) and a device type (DT) through the serial input connection of the first device;
• determining the DT of the device from the received DT;
• and
• providing an ID in response to a determination result.

An apparatus for producing a device identifier at a first device coupled to a second device in a serial interconnection configuration, the first device having a serial input connection coupled to a serial output connection of a previous device in the serial interconnection configuration, the second device having a serial input connection coupled to a serial output connection of the first device, the apparatus comprising:

• a receiver for receiving a device identifier (ID) and a device type (DT) through the serial input connection of the first device;
• a determiner for determining the DT of the first device from the received DT;
• and
• an ID producer for producing an ID in response to a determination result.

A method for determining a device identifier of one of a plurality of devices in a serial interconnection configuration, the method comprising:

• receiving a first value corresponding to a device identifier (ID) and a second value corresponding to a device type (DT);
• comparing the second value to a device type number (DTN) stored at a first device;
• and
• producing a match signal that indicates whether the second value corresponds to the DTN.

A method for assigning a device identifier at a first device coupled to a second device in a serial interconnection configuration, the first device having a serial input connection coupled to a serial output connection of a previous device in the serial interconnection configuration, the second device having a serial input connection coupled to a serial output connection of the first device, the method comprising:

• receiving a device type (DT) through the serial input connection of the first device;
• determining the DT of the device from the received DT;
• receiving a device identifier (ID) through the serial input connection of the first device;
• and
• producing an ID in response to the determination result.

A method for assigning a device identifier for a plurality of mixed type memory devices in a serial interconnection configuration, a first device having a serial input connection coupled to a serial output connection of a previous device, a second device having a serial input connection coupled to a serial output connection of the first device, the method comprising:

• receiving a device type (DT);
• holding the received DT at each of the devices;
• determining whether the DT matches a reference DT associated with each of the devices;
• providing a device identifier (ID) to one of the devices, through the serial input connection of that device;
• and
• at the device wherein the ID is provided, conducting an ID assignment in response to the determination result at that device.
