Abstract
A data storage device includes a controller, one or more memory devices and one or more passive components encapsulated in a single package. The controller, the memory devices and the passive components are directly mounted to a printed circuit board (PCB) of the data storage device. A position of the controller with respect to the one or more memory devices enables the data storage device to use shorter signal traces. Shorter signal traces leads to improved read and/or write speeds of the data storage device along with other benefits.
Claims20
A data storage device, comprising:
- a printed circuit board (PCB);
- a controller mounted directly to a surface of the PCB;
- a memory device mounted directly to the surface of the PCB and communicatively coupled to a signal trace associated with the PCB, the signal trace establishing a communication path between the memory device and the controller;
- and
- a cover encapsulating the controller and the memory device.
A method for assembling a data storage device, comprising:
- coupling a controller to a surface of a printed circuit board (PCB);
- coupling one or more passive components to the surface of the PCB;
- performing a reflow soldering process to secure the controller and the one or more passive components to the surface of the PCB;
- coupling a memory device to the surface of the PCB;
- electrically coupling the memory device to a signal trace associated with the PCB;
- and
- encapsulating the controller, the one or more passive components and the memory device with a single cover.
A data storage device, comprising:
- a printed circuit board (PCB);
- a first storage means mounted directly to a surface of the PCB and communicatively coupled to a first signal means associated with the PCB;
- a second storage means mounted directly to the surface of the PCB and communicatively coupled to a second signal means associated with the PCB;
- a controller means mounted directly to the surface of the PCB between the first storage means and the second storage means and being communicatively coupled to the first storage means using the first signal means and being communicatively coupled to the second storage means using the second signal means;
- and
- a covering means encapsulating the first storage means, the second storage means and the controller means.
