Internal RFID Tag Integration in Memory Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-value digital memory devices such as DIMM modules and flash cards face challenges in secure tracking and identification due to the risk of external RFID labels becoming detached, leading to potential theft and counterfeiting, as they are expensive to manufacture and require reliable internal identification methods.
Innovation Solution
Integration of an RF integrated circuit chip and UHF antenna traces onto a multi-layer laminated rigid glass-epoxy substrate within the memory devices, creating a tamper-proof internal RFID tag that is embedded between layers or beneath a cover, ensuring the product information is securely stored and protected.

Engineering Contradiction Analysis
1Reliability
If an external RFID label is applied to identify and track memory products, then identification and tracking capability is improved, but the label may become separated or peeled away from the product, causing loss of information
Solution Approach 1:
The RFID tag is integrated directly into the memory device structure by mounting the RF chip and forming antenna traces on the printed wiring board substrate, merging the identification function with the device itself. This eliminates the separate external label that could detach, as the RFID components become part of the device's internal structure.
2Quantity of substance
If high-capacity memory integrated circuits are used to increase storage capacity, then memory capacity is improved, but manufacturing cost increases, making products vulnerable to theft and counterfeiting
Solution Approach 1:
The integrated RFID tag serves as an intermediary security mechanism that provides authentication and tracking capabilities for high-capacity memory devices. This allows manufacturers to implement security measures against theft and counterfeiting without changing the memory capacity itself, enabling the use of high-capacity circuits while mitigating the associated risks through the RFID identification system.

AI summary
A dual in-line memory module (DIMM) and a digital flash card are disclosed including an internal, built-in RFID tag in which identification and product information is contained. The RFID tag has an RF integrated circuit chip and antenna traces spreading outwardly therefrom to permit access to the information contained by the RF chip. In the case of a DIMM, the RF integrated circuit chip and its antenna traces are located on top of or between the layers of a multi-layer laminated printed wiring board substrate. In the case of a digital flash card, the RF integrated circuit chip and its antenna traces are preferably located on top of a multi-layer printed wiring board substrate and then encapsulated within a molded cover. In the alternative, the RF chip and its antenna traces are attached to the inside of a cover that extends over and is spaced above the printed wiring board substrate.
