Connector assembly with integrated data and backup energy connections

A memory sub-system comprising:

• a first printed circuit board that comprises:
• a memory sub-system controller;
• power circuitry;
• and
• a host connector configured to electrically couple the memory sub-system to a host system;
• a second printed circuit board that comprises a set of memory devices;
• a backup energy source;
• and
• a connector assembly configured to electrically couple together the first printed circuit board and the second printed circuit board, to electrically couple the first printed circuit board to the backup energy source, the connector assembly comprising:
• a first slot that receives a first edge of the first printed circuit board, the first edge being inserted into the first slot, the first slot comprising a first plurality of electrically-conductive biased contacts configured to electrically couple with corresponding electrically-conductive surface contacts disposed on the first edge;
• and
• a second slot that receives a second edge of the second printed circuit board, the second edge being inserted into the second slot, the second slot comprising a second plurality of electrically-conductive biased contacts configured to electrically couple with corresponding electrically-conductive surface contacts disposed on the second edge, a first set of electrically-conductive biased contacts of the first plurality being electrically coupled to a second set of electrically-conductive biased contacts of the second plurality, the first slot and the second slot being positioned such that the first printed circuit board and the second circuit board are stacked in parallel in a spaced relationship;
• and
• a set of electrical connectors configured to be electrically coupled to the backup energy source, a third set of electrically-conductive biased contacts of the first plurality being electrically coupled to the set of electrical connectors.
