This paper presents voltage controlled MRAM (VCM) with novel fast read/write circuits for nonvolatile ultra-large last level cache. Further, write error rate has dramatically been reduced by thermal stability factor control using “continuous read-write-verify” scheme. Read error rate has also improved with “read-disturb-free non-destructive-self-reference read” with unipolar write of VCM.
针对非易失性超大末级缓存,提出了一种具有新型快速读写电路的压控MRAM (VCM)。此外,通过使用“连续读-写-验证”方案控制热稳定因子,大大降低了写入错误率。采用VCM单极写入的“无读干扰非破坏自引用读”也提高了读错误率。

A 1 MHz 4 ppm temperature-stable micro-oven μOven) controlled monolithic CMOS-MEMS oscillator has been demonstrated in this work, exhibiting heating power in sub-mW across the 100°C temperature span. The proposed novel isothermal μOven platform consists of dual heaters, one of which stabilizes the resonator temperature while the other of which serves as built-in self-test (BIST) to mimic ambient temperature, and a resistive temperature detector (RTD) for local resonator temperature monitoring. By adapting the constant-resistance (CR) feedback temperature control scheme, the integrated 1 MHz CMOS-MEMS oscillator shows a maximum frequency inaccuracy of only 4 ppm during a fast temperature ramp across the 94°C testing span (i.e., < 43 ppb/°C). The oscillator circuit shows a worst-case bias instability of 60 ppb and phase noise (PN) of −105 dBc/Hz at 1-kHz offset (Q = 1,700).
在这项工作中,已经展示了一个1 MHz 4 ppm温度稳定的微烤箱(μ烤箱)控制的单片CMOS-MEMS振荡器,在100°C的温度范围内显示出亚mw的加热功率。所提出的新型等温μOven平台由两个加热器组成,一个用于稳定谐振腔温度,另一个用于模拟环境温度的内置自检(BIST),以及一个用于局部谐振腔温度监测的电阻式温度检测器(RTD)。通过采用恒阻(CR)反馈温度控制方案,集成的1 MHz CMOS-MEMS振荡器在94°C测试范围(即< 43 ppb/°C)的快速温度斜坡期间显示最大频率误差仅为4 ppm。在1 khz偏置(Q = 1700)时,振荡器电路的最坏情况偏置不稳定性为60 ppb,相位噪声(PN)为- 105 dBc/Hz。

We report the first ferroelectric (FE) HfZrOx (HZO) Ge and GeSn pMOSFETs with sub-60 mV/decade subthreshold swing (SS) (40∼43 mV/decade), negligible hysteresis, and enhanced Ids. With a RTA at 450 oC, FE devices with reduced hysteresis of 40∼60 mV demonstrate the significantly improved SS and Ids characteristics compared to control devices without FE, owing to the negative capacitance (NC) effect induced by HZO. FE Ge and GeSn pFETs achieve 22% and 20% Ids enhancement than control devices, respectively, at the drive voltage of 1.0 V. NC effect in FE devices is proved by the gate leakage and inversion capacitance characteristics.

Quantum computing is no longer a future technology. Recent advances in D-Wave computers based on quantum annealing and superconducting devices, and the demonstration of long spin decoherence times in isotopically-enriched Si qubits, have accelerated the research and development of this technology. The remaining challenge is large scale integration of qubits. Physically-defined coupled quantum dots (QDs) on silicon-on-insulator substrates represent potential multiple scaled qubits. This work demonstrated the fabrication of coupled QDs with control gates and charge sensor single-electron transistors, the observation of Pauli spin blockade and the control of a few electron regimes, as well as triple QDs and p-channel operation.

High performance and reliability Ge channel CMOS with a MoS2 capping layer 具有MoS2封盖层的高性能和可靠性Ge通道CMOS

High performance Ge CMOS with quantum well-structured channels has been successfully realized using a single MoS2 capping layer. Thanks to a large valence band offset (0.43 eV) and conduction band offset (0.5 eV) between the two-layers-thick MoS2 and the Ge substrate, both holes and electrons within the Ge p- and n-MOSFETs are confined into Ge channels and the scattering due to the traps in gate stacks is suppressed effectively. As a result, the MoS2/Ge p- and n-MOSFETs exhibit much improved hole and electron mobilities, as well as the improved device reliability behaviors.
利用单个MoS2封盖层成功实现了具有量子结构良好通道的高性能Ge CMOS。由于两层厚的MoS2和Ge衬底之间存在较大的价带偏移(0.43 eV)和导带偏移(0.5 eV), Ge p-和n- mosfet内的空穴和电子都被限制在Ge沟道中,栅极堆叠中陷阱引起的散射被有效抑制。结果,MoS2/Ge p-和n- mosfet表现出更好的空穴和电子迁移率,以及更好的器件可靠性行为。

A novel approach to technology integration of system-on-chip RF Front-End Module (FEM) is presented. Device design to achieve best-in-class extended drain power mosfet (EDNMOS) with Ron of 1.6Ohm-mm and fT >39GHz is discussed. This is followed by an analysis of a high performance switch device integrated via selective silicon thinning.
提出了一种新的系统级射频前端模块技术集成方法。讨论了实现Ron为1.6 ω -mm、fT >39GHz的一流扩展漏极功率场效应管(EDNMOS)的器件设计。接着分析了一种通过选择性硅薄化集成的高性能开关器件。
