The rapid complexity growth of electronic systems nowadays increases their vulnerability to hacking, such as fault injection, including insertion of glitches into the system clock to corrupt internal state through timing errors. As a countermeasure, a frequency locked loop (FLL) based clock glitch detector is proposed in this paper. Regulated from an external supply voltage, this FLL locks at 16-36X of the system clock, creating four phases to measure the system clock by oversampling at 64-144X. The samples are then used to sense the frequency and close the frequency locked loop, as well as to detect glitches through pattern matching. Implemented in a 5nm FINFET process, it can detect the glitches or pulse width variations down to 3.125% of the input 40MHz clock cycle with the supply varying from 0.5 to 1.0V.
电子系统复杂性的快速增长增加了它们对黑客攻击的脆弱性,例如故障注入,包括通过定时错误在系统时钟中插入小故障来破坏内部状态。作为一种对策,本文提出了一种基于锁频环(FLL)的时钟故障检测器。由外部电源电压调节,该FLL锁定在系统时钟的16-36X,创建四个相位,通过在64-144X过采样来测量系统时钟。然后,这些样本用于检测频率并关闭锁频环,以及通过模式匹配检测故障。在5nm FINFET工艺中实现,它可以检测到输入40MHz时钟周期的3.125%的故障或脉宽变化,电源从0.5到1.0V不等。

This work describes the highest feature density CMOS-based DNA synthesizer, where individually addressable sub-μm pixels generate acid in situ for deprotection. A new redox chemistry enables this at low voltages. Implemented in 65nm CMOS, electrodes as small as 0.6μm2 were implemented, and oligos up to 100 nucleotides (nt) were synthesized.

This work demonstrated the monolithic 3D (M3D) integrated red micro-LED display on Si CMOS driver IC. We achieved a very high pixel density of 1600 PPI by epitaxial layer engineering and low-temperature process design for the micro- display application. M3D sequential integration on pre- fabricated Si CMOS driver IC allows lithographic alignment for the pixel definition, providing high-resolution and the largest emission area per pixel pitch. Furthermore, the low-temperature process provided the lowest standby power among ever reported micro-LED displays. We believe that this work would be one of the milestones for future ultra-high-resolution displays.

Learning graph structured data from limited examples on-the-fly is a key challenge to smart edge devices. Here, we present the first chip-level demonstration of few-shot graph learning which homogeneously implements both the controller and associative memory of a memory-augmented graph neural network using a 1T1R resistive random-access memory (RRAM). Leveraging the in-memory computing paradigm, we validated the high end-to-end accuracy of 78% (GPU baseline 80%) and robustness on node classification of CORA dataset, while achieved 70-fold reduction in latency and 60-fold reduction in energy consumption compared with conventional digital systems.

In this work, we investigate the thermal issues of top-gated (TG), ultrathin, atomic layer deposition (ALD) grown, back-end-of-line (BEOL) compatible indium oxide (In2O3) transistors by observation and visualization of the self-heating effect (SHE) using high-resolution thermo-reflectance (TR) measurement. SHE is alleviated by highly resistive silicon (HR Si) substrate with high thermal conductivity (κSi). The increased temperature (ΔT) of the devices on HR Si substrate is roughly 6 times lower than that with SiO2/Si substrate. Furthermore, thermal simulation with a finite-element method exhibits exceptional agreement to ΔT distribution with experimental results. By thermal engineering, TG In2O3 transistors with channel thickness (Tch) of 1.8 nm and high drain current (ID) up to 2.65 mA/µm are achieved.

We demonstrate a multi-pillar (MP) spin-orbit torque (SOT)-MRAM concept, which enables lower write current and high-density integration. We experimentally demonstrate the selective write operation of multi-bits in CMOS-compatible 300mm integrated top-pinned perpendicular MTJs. Multiple MTJs on a shared SOT track can be individually selected by gate voltages and independently switched by sub-ns pulses with 30% reduction in operation current. Our concept of selective operations with less transistors and lower writing energy will significantly enhance the density and energy efficiency of SOT-MRAM.

We proposed a Si/III-V hybrid waveguide photodetector consisting of an ultrathin InGaAs membrane and Si slot waveguide, enabling low capacitance and high responsivity simultaneously. The strong optical confinement in a Si slot waveguide enhanced optical absorption in the InGaAs membrane. As a result, we successfully demonstrated high responsivity of 1 A/W and sufficiently small capacitance of 1.9 fF to realize a receiver-less (TIA-less) system.

Compute-in-memory (CIM) accelerators based on run-time reconfigurable designs have shown great promise in speeding up deep neural network (DNN) inferencing. Here, we present back-end-of-the-line (BEOL) compatible Indium Tungsten Oxide channel ferroelectric transistors (IWO FeFET) as signal routing switches (RS) for monolithic 3D (M3D) CIM accelerator. We demonstrate 2.45 GHz measured cutoff frequency (fT) for the transistor and greater than 11.5 GHz intrinsic fT by de-embedding transistor extrinsic parasitics obtained through developed small-signal equivalent circuit model. Pass-transistor configuration measurements show less than 250ps of added delay and 15dB of isolation at 2.5GHz between programmed and erased states. Run-time reconfigurable operation of a 4-way routing switch is experimentally demonstrated with excellent selectivity and endurance greater than 1010 cycles. System level benchmarking of a M3D CIM accelerator employing IWO FeFET RS and weights performed on real-word DNN models shows 2.5x improvement in energy efficiency and >10% gain in area efficiency compared to 7nm SRAM design.
基于运行时可重构设计的内存计算(CIM)加速器在加速深度神经网络(DNN)推理方面显示出巨大的前景。在这里,我们提出了后端(BEOL)兼容的氧化铟钨沟道铁电晶体管(IWO FeFET)作为单片3D (M3D) CIM加速器的信号路由开关(RS)。通过建立的小信号等效电路模型,通过去嵌入晶体管的外部寄生得到晶体管的测量截止频率(fT)为2.45 GHz,本征频率(fT)大于11.5 GHz。通过晶体管配置测量显示,在2.5GHz编程和擦除状态之间,增加的延迟小于250ps,隔离小于15dB。实验证明了4路路由开关的运行时可重构操作具有优异的选择性和大于1010个周期的耐用性。采用IWO FeFET RS和权重的M3D CIM加速器在实际DNN模型上进行的系统级基准测试显示,与7nm SRAM设计相比,能效提高了2.5倍,面积效率提高了>10%。

Here, we present back-end-of-the-line (BEOL) compatible Indium Tungsten Oxide channel ferroelectric transistors (IWO FeFET) as signal routing switches (RS) for monolithic 3D (M3D) CIM accelerator. We demonstrate 2.45 GHz measured cutoff frequency (fT) for the transistor and greater than 11.5 GHz intrinsic fT by de-embedding transistor extrinsic parasitics obtained through developed small-signal equivalent circuit model. Pass-transistor configuration measurements show less than 250ps of added delay and 15dB of isolation at 2.5GHz between programmed and erased states. Run-time reconfigurable operation of a 4-way routing switch is experimentally demonstrated with excellent selectivity and endurance greater than 1010 cycles. System level benchmarking of a M3D CIM accelerator employing IWO FeFET RS and weights performed on real-word DNN models shows 2.5x improvement in energy efficiency and >10% gain in area efficiency compared to 7nm SRAM design.","PeriodicalId":332454,"journal":{"name":"2022 IEEE Symposium on VLSI Technology and Circuits (VLSI Technology and Circuits)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124735902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a unique hybrid integration platform for wafer scale passive assembly of electronics and photonics devices using a CMOS based Optical Interposer. Our optical interposer enables seamless communications between electronics and photonics chips that are assembled on it using visually assisted passive flip chip bonding techniques. This unique integration platform is the first such platform in the industry adapted to directly modulated lasers and enables the world’s smallest single chip Transmit/Receive Optical engine for 100G-400G optical engines.
