Solid state drive interface controller and method of controlling solid state drive interface

A method of controlling communication of data between a host and a solid state drive (SSD), the method comprising:

• receiving first interface information corresponding to a first command interface from an interface information storage unit;
• receiving second interface information corresponding to a second command interface from the interface information storage unit;
• determining a first activation status and a first allocated capacity of the first command interface according to the first interface information, the first allocated capacity corresponding to a portion of a total capacity of the SSD;
• determining a second activation status and a second allocated capacity of the second command interface according to the second interface information;
• and
• communicating the data between the host and the SSD via at least one of the first and second command interfaces in accordance with the first and second activation statuses and the first and second allocated capacities, respectively.

A solid state drive (SSD) interface controller, comprising:

• a plurality of command interfaces configured to communicate data between a host interface and an SSD;
• a plurality of registers configured to store interface information corresponding to the plurality of command interfaces, the interface information indicating whether each of the plurality of command interfaces is activated or deactivated, and allocating a capacity to each of the plurality of command interfaces, each capacity corresponding to a portion of a total capacity of the SSD;
• and
• an interface power management unit configured to remove power from each of the plurality of command interfaces that is deactivated further to the corresponding interface information.
