Abstract

An example device in accordance with an aspect of the present disclosure includes a unibody socket to receive a memory module that is to interface with a computing system. A portion of the unibody socket extends into a latch extension. The latch extension is to retain the memory module based on a positive locking latch retention force that is to increase in response to an unseating force of the memory module, to prevent removal of the memory module while the latch extension is in a latched position.

First claim

What is claimed is:

1. A device comprising:
a unibody socket to receive a memory module that is to interface with a computing system, wherein a portion of the unibody socket extends into a latch extension;
wherein the latch extension is to retain the memory module based on a positive locking latch retention force that is to increase in response to an unseating force of the memory module, to prevent removal of the memory module while the latch extension is in a latched position; and
wherein a flex region of the latch extension provides a flexing axis underneath the memory module about which the latch extension flexes to urge inward a tip of the latch extension.

2. The device of claim 1 , wherein the latch extension is to provide the latch retention force based on a positive latching torque acting about the flex region of the latch extension.

3. The device of claim 2 , wherein the latch extension includes a contact region to provide the latch retention force to the memory module; and
wherein the flex region is offset from the contact region to provide the positive latching torque.

4. The device of claim 3 , wherein the latch retention force is resolvable to a first component vector, along an axis between the contact region and the flex region, and a second component vector perpendicular to the first component vector and extending away from the latch extension.

5. The device of claim 2 , wherein the flex region is based on a region of the latch extension that emerges from the unibody socket.

6. The device of claim 5 , wherein the flex region is curved.

7. The device of claim 1 , wherein the latch extension includes a latch lead-in that is to cause the latch extension to deflect from the latched position to an unlatched position in response to receiving the memory module.

8. The device of claim 1 , wherein the latch extension includes a grip region to facilitate flexing of the latch extension about a flex region of the latch extension.

9. The device of claim 1 , wherein the unibody socket includes a guide extension extending from the unibody socket to stabilize insertion of the memory module into the unibody socket.

10. The device of claim 9 , wherein the guide extension includes a guide extension lead-in to guide the memory module into insertion alignment with the unibody socket.

11. A computing system comprising:
a unibody socket to receive a memory module that is to interface with a computing system, wherein a first portion of the unibody socket extends into a latch extension, and a second portion of the unibody socket extends into a guide extension;
wherein the guide extension is to stabilize insertion of the memory module;
wherein the latch extension of the unibody socket is to retain the memory module based on a positive locking latch retention force that is to increase in response to an unseating force of the memory module, to prevent removal of the memory module while the latch extension is in a latched position; and
wherein a flex region of the latch extension provides a flexing axis underneath the memory module about which the latch extension flexes to urge inward a tip of the latch extension.

12. The computing system of claim 11 , wherein the unibody socket is to interface with a dual in-line memory module (DIMM).

13. The computing system of claim 11 , wherein the unibody socket is to interface with a low-profile memory module.

14. A method, comprising:
retaining a memory module seated in a unibody socket of a computing system, based on a latch extension of the unibody socket that is flexible between an unlatched position and a latched position; and
generating, by the latch extension, a positive locking latch retention force that is to increase in response to an unseating force of the memory module, to prevent removal of the memory module from the unibody socket while the latch extension is in the latched position;
wherein a flex region of the latch extension provides a flexing axis underneath the memory module about which the latch extension flexes to urge inward a tip of the latch extension.

15. The method of claim 14 , further comprising applying the latch retention force to the memory module based on a contact region of the latch extension; and
applying, toward the unibody socket, a positive latching torque about the flex region of the latch extension, based on the flex region being offset from the contact region.
