Attopsemi Technology product offering
Product offeringCore offering
Attopsemi designs, develops, and licenses proprietary I-fuse one-time programmable (OTP) memory intellectual property (IP) for semiconductor manufacturers. The IP is delivered as silicon-verified hard macros in standard logic CMOS processes from 0.7um to 7nm without extra masks or charge pumps, and is licensed to foundries and integrated device manufacturers (IDMs) for embedding into customer chips serving automotive, IoT, biometric, sensor, power management, and MCU applications.
Product overview
Attopsemi Technology is a one-time programmable (OTP) intellectual property (IP) provider offering a portfolio of proprietary fuse-based OTP solutions built entirely on standard logic CMOS processes without additional masks or special process steps. The core product family consists of three distinct I-fuse® technology variants — I-fuse® (the foundational non-explosive fuse technology), I-fuse® S3 (a super-small and scalable peripheral architecture variant), and I-fuse® Replaser (a laser fuse replacement) — each addressing different segments of the OTP market from legacy nodes through 7nm FinFET and beyond. I-fuse® technology uses a physics-based programming mechanism below thermal runaway and above electromigration threshold, distinguishing it from conventional eFuse and anti-fuse approaches. The technology is licensed to leading foundries and integrated into customer semiconductor products across automotive, IoT, biometric, sensor, power management, and MCU applications.

Products and services
- I-fuse® Non-explosive, fuse-based one-time programmable (OTP) memory IP built on standard logic CMOS processes without extra masks or special process steps. Qualified from 0.7um to 22nm and beyond, supports high reliability without redundancy, compact size, low program/read voltage, low power consumption, and wide temperature operation. Uses physics-based programming below thermal runaway via electromigration.
- I-fuse® S3 Super-Small and Scalable variant of I-fuse OTP using a novel array architecture that delivers ~50% smaller IP area than the prior generation. Scales following Moore's Law for small to medium-sized OTP applications. Targets compact form-factor designs including biometric, sensor, and IoT ICs.
- I-fuse® Replaser Direct replacement for traditional laser fuse OTP solutions. Provides extremely low programming voltage and time, post-packaging programmability, ultra-low read voltage/current, ultra-small area (64-bit density in under 100 µm²), soft programming capability for pre-test data acquisition, and wide temperature operation from -40°C to 150°C. Targets customers seeking to replace legacy laser fuse solutions without altering packaging flows.

Attopsemi Technology competitors and assessment
Company assessmentRegional players
- Chipone Technology: Chipone Technology is a Chinese display driver and mixed-signal IC company with embedded NVM requirements for display calibration and trimming. While it is primarily a chip company rather than an IP licensor, it overlaps with Attopsemi's OTP use cases in display driver ICs, especially for the China supply chain.
- Shanghai Fudan Microelectronics: Shanghai Fudan Microelectronics is a major Chinese fabless IC company that develops and licenses its own embedded OTP/MTP NVM IP for smart card, security, and MCU products. It is a comparable competitor primarily serving the China domestic market that Attopsemi does not directly address.
- Macronix International: Macronix is a Taiwan-headquartered non-volatile memory company with proprietary NVM technology and embedded memory IP offerings. It is comparable to Attopsemi as a Taiwan-rooted NVM specialist, though Macronix also manufactures standalone flash/NOR memory products alongside its embedded IP.
Broad incumbents
- Synopsys: Synopsys is the largest EDA and IP vendor globally, and through its acquisitions of Sidense and Kilopass it sells competing OTP/eFuse/anti-fuse memory IP as part of its DesignWare portfolio. It bundles OTP IP with full-stack design tools, giving it a far broader commercial footprint than Attopsemi's specialist offering.
- Renesas Electronics: Renesas, through its acquisitions of Dialog Semiconductor and Intersil, offers embedded OTP/MTP NVM IP in its automotive MCU and analog platforms. As a broad incumbent IDM, Renesas competes with Attopsemi in serving automotive and industrial customers who can either license external OTP IP or use in-house alternatives.
Direct peers
- Kilopass Technology (Synopsys): Kilopass pioneered antifuse OTP IP and was acquired by Synopsys in 2018. It overlaps with Attopsemi in offering anti-fuse OTP for security keys, configuration, and trim in CMOS processes from legacy nodes through advanced nodes.
- Sidense Corp. (Synopsys): Sidense developed 1T-Fuse-based antifuse OTP IP across foundries including GLOBALFOUNDRIES and TSMC, and was acquired by Synopsys in 2022. It is a category-defining direct competitor to Attopsemi's I-fuse in the same OTP memory IP niche.
- eMemory Inc. eMemory Inc. is a Taiwan-headquartered, publicly listed OTP and MTP NVM IP company offering NeoFuse, NeoEE, NeoMTP, and NeoPUF solutions. It is Attopsemi's most direct competitor, serving overlapping foundry partners and the same fabless customer base for code storage, trim, and security applications.
