Abstract
Provided herein may be a storage device and a printed circuit board for a solid state drive. The storage device may include a substrate including a conductive via, a plurality of memory devices mounted on a top surface of the substrate, a memory controller mounted on the top surface and electrically connected to the conductive via, and a port formed on a bottom surface of the substrate and electrically connected to the conductive via and a host device.
Claims22
A storage device comprising:
- a substrate including a conductive via extending between a top surface and a bottom surface of the substrate;
- a memory controller mounted on the top surface of the substrate;
- a plurality of memory devices mounted on the top surface and electrically coupled to the memory controller;
- and
- a port disposed on the bottom surface of the substrate and electrically coupled to the memory controller through the conductive via,
- wherein a signal path between the memory controller and the port is formed through the conductive via without a horizontal interconnect trace.
A printed circuit board for a solid state drive, comprising:
- a multilayer substrate including a conductive via;
- a connection terminal formed on a top surface of the substrate to connect a memory controller to the conductive via;
- and
- a port formed on a bottom surface of the substrate to connect the conductive via to a host device,
- wherein the conductive via provides a direct electrical path between the connection terminal and the port, thereby reducing channel length between the memory controller and the host device.
A storage device, comprising:
- a substrate including a conductive via;
- a plurality of memory devices mounted on a top surface of the substrate;
- a memory controller mounted on the top surface of the substrate and electrically connected to the conductive via;
- and
- a port formed on a bottom surface of the substrate and electrically connected to the conductive via and a host device,
- wherein the port includes a plurality of pins disposed in a port area of the bottom surface of the substrate, the port area at least partially facing, across the substrate, an area of the top surface in which the memory controller is disposed.
A printed circuit board for a solid state drive, comprising:
- a multilayer substrate including a conductive via extending between a top surface and a bottom surface of the substrate;
- a connection terminal disposed on the top surface and configured to electrically couple a memory controller to the conductive via;
- and
- a port disposed on the bottom surface and electrically coupled to the conductive via and a host device,
- wherein the port is disposed in a port area of the bottom surface that is aligned with, across the substrate, an area of the top surface in which the memory controller is to be mounted.
