Zero-Error Systems (ZES) Unveils ‘Voter-Module with EDAC Software’ for Data-flips/Soft-error detection and correction in Memories for FPGA/GPU subsystems
Monday, 2nd February 2026, Singapore
Zero-Error Systems (ZES) is excited to announce the launch of the ‘Voter-Module with EDAC Software’ ZM-VF01A, the industry’s 1st Radiation-Hardened by Design (RHBD) Voter-module for TMR (Triple Modular Redundancy) with proprietary Error-Detection-and-Correction (EDAC) software, that efficiently corrects ‘Data-flips/ Soft-errors’ in memories induced by radiation events (SEU- Single Event Upset) explicitly designed for advanced satellite applications.
Data Integrity in Space Environments
In space, electronic systems are exposed to natural radiation from the Sun and deep space. These high-energy particles can occasionally interact with onboard electronics and momentarily alter stored data—commonly referred to as data-flips. Data-flips in space usually refer to Single Event Upsets (SEUs)—bit errors caused by radiation interacting with electronic devices, in particularly the data stored in memories (including DDR4, eMMC flash, embedded SRAMs, etc.) for a computational payloads with FPGA/GPU for on-board data processing.
To ensure uninterrupted and reliable operation, modern space systems employ advanced resilience techniques such as Triple Modular Redundancy (TMR) with intelligent voting. In this architecture, critical computations are performed simultaneously across three independent logic paths, and a TMR Voter continuously compares their outputs. If a transient data-flip occurs in one path, the voter automatically selects the correct majority result—in real time and without service interruption.
For enhanced data integrity, ZES’ patented hardware-cum-software hybrid solution, with a triple-modular-redundancy (TMR) radiation-hardened Voter-IC, with Ferroelectric Random Access Memory (FRAM) memory which stores a small portion of the most-critical encoded raw data information. The software involves a proprietary Error-Detection-and-Correction (EDAC) c-code in the MCU/FPGA/GPU to encode/decode the raw data. The hybrid solution detects/corrects multiple-bit raw data errors that can be stored in any memory, e.g., embedded memory inside MCU/FPGA/GPU or external memories (e.g., DDR4, eMMC).
ZES’ hybrid solution is coined as “ZEDAC”, featuring lower SEUs (>50x to 2,000x lower) than the purely-hardware and purely-software solutions. Other methods such as software-based single-event-effect (SEE) management are also adopted. ZES’ Voter-IC ZES400 on the module is heavy-ion irradiation-tested, and features SEL-free with at least 110 MeV.cm2/mg, with Total Ionizing Dose (TID) tested up to 300K rad (Si) @ Co-60.
TMR Voter-Module with EDAC Software (ZM-VF01A)
ZM-VF01A is a radiation-hardened Triple-Modular-Redundancy (TMR) Voter module embodying a ZES400 Voter-IC with three FRAM (1M-bit) implemented in TMR. The ZES400 Voter-IC embodies 4-channel voting circuits where one of the channels is used to vote the outputs of the FRAMs. An additional voter channel is available for supporting TMR for another signal where necessary. The ZM-VF01A features ultra-low soft error, suitable for storing critical data storage and/or supporting ZES error-detection-and-correction (ZEDAC) algorithms.
Ultra-low soft errors (ULSE) correction in NVIDIA® Jetson AGX OrinTM GPU systems in Space systems
TMR Voter-module (ZM-VF01A) is a compact plug-in-play module (11.8 x 11.8 mm) which can be integrated to the existing payload/subsystems without re-designing the circuit, with a connector adaptor-board to the existing payload. For illustration, below is the NVIDIA® Jetson AGX OrinTM GPU module system integrated with ZM-VF01A plug-in-play solution for SEU mitigation for memories protecting/correcting data-flips/ AI-models on the computation payload.
The target market for this ‘Voter-module/EDAC Software’ includes satellite’s payloads with on-board memories storing critical data for subsystems in On-Board Computers (OBC), telemetry systems, camera image processing, SAR communication modules and for edge-computation/ AI systems with GPU/FPGA processors for protection of AI-models/ computational data.
As the demand for satellite-based edge-computing, artificial intelligence (AI), and data centers in space grows exponentially, the ZM-VF01A Voter-module addresses a critical need in space electronics protecting data in high-performance computational payloads using GPU/NPU/FPGA on-board satellite subsystems that face increased vulnerability to SEU effects caused by radiation induced data-flips/soft-errors in the stored data.
