Storage devices and methods of operating storage devices

A method of operating a storage device, the method of comprising:

• providing a storage controller and a plurality of nonvolatile memory devices on a printed circuit board (PCB);
• providing a connector with a plurality of connection terminals in the PCB;
• providing data transmission lines electrically connecting the storage controller and the plurality of nonvolatile memory devices in the PCB;
• providing at least one passive filter between the connector and the storage controller in the PCB;
• performing an equalization, using the at least one passive filter, on any one or any combination of a signal provided to the storage controller and a signal provided from the storage controller;
• and
• communicating, using the storage controller, with an external host through the connector.

A storage device, comprising:

• a printed circuit board (PCB);
• a plurality of nonvolatile memory devices provided on the PCB;
• a connector provided in the PCB, the connector comprising a plurality of connection terminals;
• a storage controller provided on the PCB, the storage controller being configured to communicate with an external host through the plurality of connection terminals and control the plurality of nonvolatile memory devices;
• and
• at least one passive filter provided in the PCB and connected between the connector and the storage controller, the at least one passive filter being configured to perform an equalization on any one or any combination of a signal provided to the storage controller and a signal provided from the storage controller, wherein:
• the at least one passive filter comprises a filter resistor and a filter capacitor connected in parallel between a first node and a second node;
• the filter resistor and the filter capacitor are provided in the PCB;
• and
• the first node is coupled to the storage controller and the second node is coupled to the connector.
