The solution is targeted at advanced AI SoCs that require high-density SRAM.
AI SoCs equipped with AI language models, data process units (DPU) and SRAM-based computing-in-memory (CIM) architectures are in increasing demand but there are real challenges when it comes to technology scaling. The drastic increase in density makes manufacturing, yield and the reliability of SRAMs crucial for smart SoCs.
Autonomous built-in self repair (BISR) technology and one-time programmable (OTP) non-volatile memory are seen as essential in overcoming challenges when it comes to embedded memory fault and yield issues.
The memory test solution, Tessent MemoryBIST from Siemens, enables comprehensive automation and integration for at-speed test, diagnosis, repair, debug and characterization of on-chip memories, while eMemory’s OTP plays an essential role in storing repair data.
The new integrated solution features OTP programming optimisation for maximised efficiency and benefits users with various SoC bus protocols.
A distinguishing capability from eFuse is that NeoFuse supports memory built-in self test (MBIST) to do in-field re-test and repair without additional costs, which is a critical advantage for high-end chip applications such as automotive applications.
"eMemory's OTP was strictly qualified by TSMC N5, N4P and N5A, which feature perfect yield, reliability, footprint and cost. The combination of Tessent MemoryBIST from Siemens and eMemory's NeoFuse OTP presents maximised efficiency in supporting clients in maintaining their AI SoC's reliability," said Chris Lu, Senior Vice President of Business Development of eMemory.
“The paradigm shift across global IC markets towards AI technologies requires innovation solutions,” said Ankur Gupta, senior vice president and general manager, Digital Design Creation Platform, Siemens Digital Industries Software. “This solution can benefit advanced AI SoC customers with fast time to market, high yields and excellent reliability at low cost. Together, this solution can help optimise power, performance and area for customers.”
