Systems, devices, and methods for selective communication through an electrical connector

A method of operating an electrical system, the method comprising:

• receiving a second electronic device into a memory socket;
• detecting an insertion of the second electronic device into the memory socket by receiving at least a first presence detect signal near a first side of the memory socket, and receiving at least a second presence detect signal near a second side of the memory socket that is opposite the first side
• disabling communication between the first electronic device and the second electronic device by keeping communication between the first electronic device and the second electronic device disabled for a predetermined time after both the first presence detect signal and the second presence detect signal are received;
• enabling communication between the first electronic device and the second electronic device;
• receiving a protocol indicator at the first electronic device from the second electronic device through a memory socket, the protocol indicator indicating a communication protocol of a plurality of different communication protocols with which the second electronic device is configured to communicate through the memory socket;
• and
• communicating with the second electronic device through the memory socket using the indicated communication protocol.

An electronic device, comprising:

• a protocol indicator generator configured to provide a protocol indicator to another electronic device through an electrical connector of a memory socket of the other electronic device, the protocol indicator indicating a particular communication protocol with which the electronic device is configured to communicate;
• a communication module configured to communicate with the other electronic device through the electrical connector using the particular communication protocol;
• and
• a mating connector configured to interface with the electrical connector, the mating connector comprising one or more pins having two pins located at opposite sides of the mating connector, and the one or more pins configured to:
• output a presence detect signal to the other electronic device through the electrical connector to enable the other electronic device to detect the electronic device, and
• contact mating pins of the electrical connector after other pins of the mating connector contact other mating pins of the electrical connector, and
• one or more protocol indicating pins for outputting the protocol indicator, wherein each of the one or more protocol indicating pins is tied to one of a high power signal defining a logic level high and a low power signal defining a logic level low in an arrangement that indicates the particular communication protocol.
