Apparatus and method for producing identifiers regardless of mixed device type in a serial interconnection
First Claim
1. A method for assigning a device identifier for a plurality of devices of mixed type 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 being adopted to at least one of the devices, the method comprising:
- receiving a device identifier (ID) and a device type (DT) as a packet through the serial input connection of the first device;
performing;
a first determination whether the DT of the device contains pre-defined data corresponding to one including all device types to provide a first determination result; and
a second determination of the DT of the device in response to the received DT to provide a second determination result; and
outputting an ID in response to the first and second determination results.

Abstract
A method and apparatus for assigning a device identifier for a plurality of devices of mixed type (e.g., DRAMs, SRAMs, MRAMs, and NAND-, NOR- and AND-type Flash memories) in a serial interconnection configuration are disclosed. One device of the serial interconnection configuration receives a device identifier (ID) and a device type (DT) as a packet through its serial input connection. A first determination is performed as to whether the DT of the device contains pre-defined data corresponding to one including all device types to provide a first determination result; and a second determination of the DT of the device is performed in response to the received DT to provide a second determination result. An ID is produced and output to a next device in response to the first and second determination results. The received ID or the produced ID is assigned to the respective devices.

4. An apparatus 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 devices being of different types, the apparatus comprising:
-
a receiver configured to receive a device identifier (ID) and a device type (DT) as a packet provided through the serial input connection of the device; a determiner configured to perform; a first determination of whether the DT of the device contains pre-defined data corresponding to one including all device types to provide a first determination result; and a second determination of the DT of the device based on the received DT to provide a second determination result; and an output ID provider configured to output an ID in response to the first and second determination results. - View Dependent Claims (5, 6, 7, 8, 9, 10)
