Ngsff and m.2 differentiation and mutual protection circuit

A solid-state drive (SSD) device, comprising:

• a first connector comprising at least one first-type pin and at least one second-type pin, the first connector capable of being connected to a corresponding connector of a host device;
• and
• at least one first detector device coupled to the at least one first-type pin and the at least one second-type pin of the first connector, the at least one first detector device to control the at least one first-type pin of the first connector to be coupled to a first voltage based on, at least in part, detecting that the at least one second-type pin of the first connector is connected to a second voltage while the SSD is connected to the corresponding connector of the host device, the first voltage being provided by the host device, and to control the at least one first-type pin of the first connector to be in a non-connected state based on, at least in part, detecting that the at least one second-type pin of the first connector is connected to a third voltage while the first connector is connected to the corresponding connector of the host device.

A solid-state drive (SSD) device, comprising:

• a first connector comprising at least one first-type pin and at least one strap-signal-type pin, the first connector capable of being connected to a corresponding connector of a host device;
• and
• at least one first detector device coupled to the at least one first-type pin and the at least one strap-signal-type pin of the first connector, the at least one detector device to control each first-type pin of the first connector to be coupled to a first voltage based on, at least in part, detecting that the at least one strap-signal-type pin of the first connector is connected to a second voltage while the first connector is connected to the corresponding connector of the host device, the first voltage being provided by the host device, and to control each first-type pin of the first connector to be in a non-connected state based on, at least in part, detecting that the at least one strap-signal-type pin of the first connector is connected to a third voltage while the first connector is connected to the corresponding connector of the host device.
