Infineon’s LPDDR Flash Memory to enable next-generation automotive E/E architectures

The SEMPER X1 LPDDR Flash provides safer, more reliable, and real-time code execution which is deemed critical for automotive domain and zone controllers. According to Infineon, the device delivers 8 times the performance of current NOR Flash memories and achieves 20 times faster random read transactions for real-time applications, enabling software-defined vehicles to deliver advanced features with enhanced safety and architectural flexibility.

Intelligence, connectivity, and complexity, along with safety and dependability requirements means that next-generation vehicles are increasingly reliant on state-of-the-art multi-core processors developed on advanced manufacturing processes.

Consequently, higher density embedded non-volatile memories are no longer seen as a viable cost option at these advanced nodes, and system architects need to consider using external NOR for code storage. These complex automotive real-time processors, however, demand more performance than current memories available on the market.

To address this, Infineon developed the SEMPER X1 with an LPDDR4 interface operating at 3.2 GBytes/sec and a multi-bank architecture to meet the performance and density requirements of domain and zone controllers.

“With the drive towards semi-autonomous vehicles and more sophisticated engine control, real-time decisions are critical to the dependability and safety of the vehicle and driver,” said Jim Handy, General Director of the semiconductor market research firm Objective Analysis. “Infineon’s LPDDR Flash memory should address these needs well in next-generation vehicles, providing real-time execute-in-place (XiP) memory and enabling it to scale independently of the processor.”
