[0002] A memory slot is a slot on the motherboard that's used to insert memory modules. It determines the type and capacity of memory supported by the motherboard. To allow for expansion, motherboards typically have several slots pre-installed to allow users to select the number of memory modules they need. This allows for additional memory expansion when the system runs low.

[0003] However, in actual use, due to cost reasons, the user may have a small single memory stick but want a larger memory stick. In this case, the larger memory stick cannot be assembled due to insufficient number of memory stick slots. Due to the limitation of the number of slots, the user has to discard the small single memory stick and repurchase a large single memory stick to meet the demand for larger memory stick, which greatly increases the cost of use. Therefore, to address the above problem, an expandable memory stick slot structure is proposed. Utility Model Content
