an actuator attached to a first end guide in the pair of end guides, wherein a user actuates a rotating and locking function of the memory module mechanism by applying a force to the actuator or to the supporting member, thereby rotating the memory module between the unlocked position and the locked position.
9. The memory module mechanism as recited in claim 8 , wherein the memory module mechanism allows insertion and removal of the memory module while in the unlocked position and restricts insertion and removal of the memory module while in the locked position.
10. The memory module mechanism as recited in claim 8 , wherein the memory module mechanism provides for an over travel rotation of the memory module mechanism in a first rotational direction in response to the force applied to the actuator or to the supporting member while the memory module mechanism is in the locked position.
11. The memory module mechanism as recited in claim 10 wherein the memory module mechanism further comprises:
a spring-loaded mechanism to rotate the memory module, in a second rotational direction opposite a first rotational direction, from the locked position to the unlocked position in response to the over travel rotation.
