Abstract
A semiconductor storage device such as an SSD includes a pliable printed circuit board (PCB) having semiconductor memory devices mounted by solder balls on first and second opposed major surfaces. The memory devices are mounted so as to be staggered and/or partially overlapping with each other on the first and second surfaces of the PCB in at least one direction. The staggered arrangement allows the PCB to flex upon warping of the memory devices mounted on the PCB.
