Apparatuses including one or more semiconductor devices and related systems

A system, comprising:

• a central processing unit connected to at least one memory device, the at least one memory device comprising a substrate supporting one or more memory chips thereon, the substrate comprising:
• an interface located proximate to a first end of the substrate and sized, shaped, and configured to provide external electrical connection to at least one semiconductor device;
• and
• hook-shaped engagement structures located proximate to, and laterally outward from, the interface, the hook-shaped engagement structures extending laterally beyond a longitudinal remainder of a lateral periphery of the substrate trailing the hook-shaped engagement structures;
• and
• wherein the at least one memory device further comprises a carrier comprising:
• posts shaped, positioned, and configured to be positioned in throats of the hook-shaped engagement structures to secure the first end of the substrate to the carrier;
• and
• sidewalls extending longitudinally from a crossbar for placement along the remainder of the lateral periphery of the substrate.

An apparatus, comprising:

• a substrate supporting semiconductor devices thereon, the substrate comprising:
• an edge connector located at a first end of the substrate and sized, shaped, and configured to provide external electrical connection to the semiconductor devices;
• and
• crook-shaped engagement structures located proximate to the first end of the substrate, and proximate to a lateral periphery of the substrate, the crook-shaped engagement structures extending laterally beyond a remainder of the lateral periphery of the substrate located on a side of the crook-shaped engagement structures opposite the first end of the substrate;
• a carrier comprising:
• columns shaped, positioned, and configured to be positioned in gaps defined by the crook-shaped engagement structures to secure the first end of the substrate to the carrier;
• and
• rails extending longitudinally from a crossbar for placement along the remainder of the lateral periphery of the substrate.
