Abstract
Description
Technical Field
[0001] This utility model relates to a memory card, specifically a CAM memory card structure. Background Technology
[0002] CAM memory cards refer to Content Addressable Memory, a type of memory that accesses data based on stored content rather than addresses. CAM quickly returns the required information through content matching, making it suitable for applications requiring high-speed lookup and matching, such as network routing, database indexing, and security checks.
[0003] Existing CAM memory cards have a complex and poorly designed structure, resulting in low space utilization and limited functionality. Furthermore, the card body lacks any protective structure on its top and bottom sides, making it susceptible to wear and tear from external objects. Therefore, the inventors have improved the structure of the CAM memory card. Utility Model Content

This memory card structure has the advantages of simple structure, reasonable design, simultaneous storage of SIM card and memory card, enhanced functionality, higher space utilization, and suitability for widespread use. The upper shell and inner shell can protect and shield the SIM card and card body, preventing the SIM card and card body from being worn by other external objects. This solves the problems mentioned in the above-mentioned technical background.
