Accelerating Data Storage in Automotive ECUs: A Shift from Traditional NVM to Keepalive Memory

Abstract Automotive Electronic Control Units (ECUs) are fundamental to managing various vehicle operations, ranging from engine performance to safety systems and driver assistance features. As vehicles become increasingly software-driven and data-centric, the efficiency and reliability of in-vehicle data storage have become critical. Conventional Non-Volatile Memory (NVM) technologies—such as EEPROM and flash—commonly used in ECUs, introduce delays due to their dependence on low-power or sleep modes for data writing. These delays can hinder real-time data logging and response, especially in safety-critical applications. This study investigates Keepalive Memory, an emerging storage solution capable of capturing data instantly, without requiring the ECU to transition into sleep states. This characteristic enables real-time data persistence while minimizing latency and power usage. Benchmark analysis shows that Keepalive memory achieves up to 72% reduction in write latency and 45% lower energy consumption per transaction compared to EEPROM. Additionally, system-wide latency improvements of up to 60 milliseconds per operation were observed, offering significant gains in responsiveness and logging speed during live vehicle operation. The paper provides a detailed comparison of Keepalive memory and traditional NVM in the context of automotive systems, analyzing their impact on real-time performance, energy efficiency, and reliability. Practical considerations for integration and scalability are also discussed. Results highlight that Keepalive memory holds strong potential to address the limitations of existing NVM in modern and future ECUs, particularly where instant data availability and system uptime are critical.
