Signal path interconnection and assembly

A data storage device comprising:

• a controller printed circuit board (PCB) supporting a controller integrated circuit (IC) and a support bracket;
• a memory PCB supported by the support bracket in spaced apart, parallel relation to the controller PCB, the memory PCB supporting at least one memory IC that has at least one corresponding connection pad located at an edge of the memory PCB;
• and
• a board edge connector coupled to the connection pads of the memory PCB on a first side of the connector, while extending no farther than the areal extent of connection pads of the memory PCB, the connector affixed to the support bracket and a flex circuit on a second side of the connector to translate the connection pads to the flex circuit and form a data signal path that interconnects the memory IC and the controller IC.

An apparatus comprising:

• a controller printed circuit board (PCB) supporting a controller integrated circuit (IC) and a support bracket;
• a first and second memory PCB each supported by the support bracket in spaced apart, parallel relation to the controller PCB, each memory PCB supporting at least one memory IC;
• and
• first and second flex circuits that respectively interconnect a first and second edge connector to a first and second interposer each positioned on the controller PCB between the respective areal extents of the controller PCB and the memory PCB to form independent data signal paths between the first and second memory PCBs and the controller IC.
