Solution Overview
Problem
Existing semiconductor memory systems face challenges in reducing design complexity and power consumption, especially in devices that perform simple functions, where the cost of implementing processing and memory resources outweighs the benefits, making them impractical for applications like IoT devices.
Innovation Solution
A wireless memory system where a processor is wirelessly coupled to a memory array, using high-frequency communication bands like EHF for data transfer, allowing network devices to share a main memory externally, reducing the need for internal memory and transceivers, and enabling efficient device-to-device communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal semiconductor memory and processing resources are implemented in each device, then data storage and processing capabilities are ensured, but design complexity and power consumption increase
Solution Approach 1:
The patent extracts the memory resource from individual devices and creates a separate, external main memory system. Devices are decoupled from local memory, allowing them to access shared memory resources wirelessly. This reduces device complexity while maintaining data storage capabilities through centralized memory architecture.
Solution Approach 2:
The patent creates a universal main memory system that serves multiple devices simultaneously. Instead of each device having dedicated memory, a single memory resource provides storage services to numerous devices, reducing overall system complexity and enabling resource sharing across the network.
2Reliability
If internal semiconductor memory and processing resources are implemented in each device, then data storage and processing capabilities are ensured, but power consumption increases
Solution Approach 1:
The patent extracts memory functionality from power-constrained devices and relocates it to a dedicated memory system. This allows devices to eliminate local memory and access external memory wirelessly, significantly reducing power consumption while maintaining data storage and processing capabilities through the shared memory resource.
3Device complexity
If devices share external memory wirelessly, then design complexity and power consumption are reduced, but transfer speed may decrease compared to local connection
Solution Approach 1:
The patent replaces the mechanical/wired connection system with a wireless communication system. Devices communicate with the main memory through wireless transceivers, eliminating physical connections while maintaining data transfer functionality. This substitution reduces device complexity by removing wired interfaces while achieving acceptable transfer speeds through wireless communication protocols.

AI summary
Methods, apparatuses, and systems related to wireless main memory for computing are described. A device may include a processor that is wirelessly coupled to a memory array, which may be in a physically separate device. The processor may execute instructions stored in and wirelessly communicated from the memory array. The processor may read data from or write data to the memory array via a wireless communication link (e.g., using resources of an ultra high frequency, super high frequency, and/or extremely high frequency band). Several devices may have a small amount of local memory (or no local memory) and may share, via a wireless communication link, a main memory array. Memory devices may include memory resources and transceiver resources; they may be configured to use one or several communication protocols over licensed or shared frequency spectrum bands, directly (e.g., device-to-device) or indirectly (e.g., via a base station).
