SCI Semiconductor secures £5 million to scale memory-safe chip production
The Sheffield-based start-up will use the funding to expand its ICENI chip family and develop next-generation hardware in the UK.
Sheffield-based cybersecurity start-up SCI Semiconductor has secured £5 million in funding to accelerate the production of its memory-safe computer chips. The investment aims to scale the company's ICENI chip family and foster the development of next-generation hardware within the UK.
The oversubscribed funding round was led by PXN Ventures and Mercia Ventures, the fund managers of the Northern Powerhouse Investment Fund II. Additional support for the round came from Osney Capital and Black Opal Ventures. Founded in 2022 by Haydn Povey, Krishna Anne, and Dr. David Chisnall, the company has already attracted significant industry interest, with Google Research signing up as a customer for the Iceni IC.
The Hardware Approach to Security
Most modern cyber-attacks exploit memory safety vulnerabilities, such as buffer overflows, which occur when traditional programming languages allow unrestricted memory access. SCI Semiconductor addresses this at the hardware level using CHERI (Capability Hardware Enhanced RISC Instructions), a framework developed by the University of Cambridge.
Unlike standard processors, CHERI-based hardware replaces simple memory address pointers with metadata that includes specific permissions and bounds. This effectively compartmentalizes memory, preventing unauthorized access and blocking common attack vectors without requiring developers to completely rewrite existing software.
Industry Implications
Solving memory safety in hardware reduces the global technology infrastructure's reliance on constant software patching, a process that is increasingly strained as AI tools identify new vulnerabilities at scale. This shift is particularly critical for high-integrity sectors, including the automotive, medical, and defense industries, where a single memory exploit can have catastrophic physical consequences.
Will Schaffer, Investment Director at Mercia Ventures, described the company's approach as an "elegant solution to a trillion-dollar problem" that has largely eluded other industry players.
The Path Forward
With the new capital, SCI Semiconductor intends to move from development into scaled production. CEO Haydn Povey noted that as AI identifies hundreds of critical vulnerabilities, it is becoming clear that vast amounts of existing technology remain open to attack.
While the company has secured a high-profile partner in Google Research, the broader adoption of CHERI-based hardware across the semiconductor industry remains the primary hurdle. The company's ability to integrate these security features into standard workflows will determine if memory-safe hardware becomes the new baseline for global computing infrastructure.
