ReRAM Controller Data Retention Without Capacitors

The patent extracts and removes the capacitor component from the data storage system. Instead of using capacitors to maintain data during power loss, the invention uses a write-amplifier circuit with a queue structure that can buffer and manage write operations without requiring additional capacitive storage elements, thereby eliminating the cost and size associated with capacitors while maintaining data integrity

The write-amplifier circuit serves multiple functions: it buffers incoming write data, manages the queue of data to be written to non-volatile memory, and maintains data integrity during power loss events. This multi-functional approach replaces the specialized capacitor component, achieving data protection without the associated cost and size penalties

The patent removes the physical capacitor component from the device architecture. The write-amplifier circuit with its queue-based data management system provides the necessary data retention capability without requiring the physical space that capacitors occupy in traditional data storage devices

The patent merges the data buffering and queue management functions directly into the write-amplifier circuit logic rather than requiring separate capacitive storage elements. This integration eliminates the need for additional physical components and reduces the overall device volume while maintaining the ability to preserve data during power loss events
