Abstract: A bridge hoard includes a printed circuit board (PCB) and a protocol converter mounted on the PCB to perform a conversion operation converting between a first communication protocol and a second communication protocol different from the first communication protocol. The bridge board further includes a first connector configured to communicate according to the first communication protocol and a second connector configured to communicate according to the second communication protocol. The bridge board additionally includes a hole formed in the PCB. The PCB is shaped as a concave polygon. The concave polygon includes a first region and a second region. The first region includes a first edge and a second edge, which extends in parallel to the first edge, along a first direction. The second region includes a third edge and a fourth edge, which extends in parallel to the third edge, along a second direction perpendicular to the first direction.

Abstract: A solid state drive (SSD) housing assembly includes an SSD housing and an extension frame. The SSD housing includes a first extension joint and a first mounting joint. The first mounting joint is a mechanism by which the housing can be mounted to an external device. The SSD housing has the form of a rectangular case in which an SSD module is held. The extension frame includes a second extension joint and a second mounting joint. The second mounting joint is a mechanism by which the frame can be mounted to the external device. The extension frame is attachable to and detachable from the SSD housing by virtue of the first extension joint and the second extension joint.

Abstract: A semiconductor memory device including a case including an upper case, a lower case, support structures extending from the lower case to the upper case, a printed circuit board (PCB) in the case and supported by the support structures, a leaf spring on a lower surface of the PCB, the leaf spring seated on support surfaces of the support structures, and a solder layer between the PCB and the leaf spring, the solder layer coupling the PCB with the leaf spring may be provided.
