Abstract
A data storage device includes a power line communication (PLC) circuit and a storage controller. The PLC circuit is coupled to a power line. The storage controller is coupled to the PLC circuit. The storage controller is configured to access a plurality of memory block. The PLC circuit is configured to carry at least one signal outputted from the storage controller on the power line, in order to transmit the at least one signal to an external device such that an operational state of the data storage device can be debugged/monitored.
Claims20
A storage control device for accessing at least one of memory blocks, the storage control device comprising:
- an interface configured to couple to a host system, wherein the interface comprises a plurality of data pins and a plurality of power pins, wherein the storage control device receives an electric power from a power source via the plurality of power pins and a power line;
- a power line communication (PLC) module, coupled to at least one of the plurality of power pins, configured to acquire an encoded signal in the power line, to decode the encoded signal from the power line to generate a decode signal;
- and
- a storage control circuit, coupled to the plurality of data pins and the power line communication module, configured to access at least one of memory blocks according to a command from the host via the plurality of data pins, to perform a corresponding program according to the decode signal of the PLC module, and to produce a response signal to the power line via the PLC module and the at least one of the plurality of power pins of the interface.
A storage control method for accessing at least one of memory blocks, the control method comprising:
- providing an interface comprising a plurality of data pins and a plurality of power pins, wherein the plurality of power pins receives an electric power from a power line;
- acquiring an encoded signal in the power line on at least one of the plurality of power pins;
- decoding, by a power line communication (PLC) module, the encoded signal from the power line to generate a decoded signal;
- and
- accessing, by a storage controller, at least one of memory blocks according to a command from a host via the plurality of data pins;
- performing, by the storage controller, a corresponding program according to the decoded signal of the PLC module to produce a response signal to the power line via the at least one of the plurality of power pins of the interface.
