The rapid growth of data-intensive applications in modern data centers is driving demand for scalable, high-speed, and energy-efficient optical interconnects. Traditional noncoherent modulation schemes, such as pulse amplitude modulation (PAM), are reaching their scalability limits at higher data rates, making coherent detection increasingly attractive due to its higher spectral efficiency. …
This article presents SHINSAI—a 586 mm2 reusable active through-silicon via (TSV) interposer addressing key challenges in multi-chiplet integration (MCI) architectures. While active interposers overcome fundamental limitations of passive counterparts by integrating functional circuitry, existing solutions face three critical constraints: 1) non-recurring engineering (NRE) costs from application-specific interposers negating chiplet reuse benefits; 2) …
This article presents kNOT, a scalable, distributed, and 2-D Network-On-Textile (kNOT) comprising miniaturized systems on chip (SoCs) and bypass SPI (bySPI) networking chiplets that together enable diverse networking and computational tasks. To preserve garment comfort and flexibility, kNOT eliminates bulky boards and interposers through direct-die attachment to embroidered yarns. The …
This article reports a 1-Tb 3-b/cell 3-D flash memory fabricated with CMOS direct bonded array (CBA) technology. Compaction of circuits and wires achieves the highest bit density in the world over 29 Gb/mm2 with 332-word line (WL) layers. The bit density is improved by 71% from a previous generation despite …
This article presents a low-jitter sub-sampling chopper phase-locked loop (SS-CPLL) that incorporates a novel chopping charge pump (C-CP) to mitigate 1/f noise in short-channel devices operating at a low supply voltage of 0.75 V. A charge-share cancellation technique is introduced to suppress ripple generated by residual charge from the previous reference …
We propose a new ping-pong (PP) charge-sharing locking (CSL) phase-locked loop (PLL) architecture that enhances the strength of charge-injection into the oscillator’s LC-tank using complementary charge-sharing capacitors during both positive and negative halves of the reference clock, effectively achieving an implicit $2times $ reference frequency multiplication. The design includes a …
This article presents a high-density, single-ended non return to zero (NRZ) chiplet I/O implemented with 3 nm CMOS technology on a 2.5-D chip-on-wafer-on-substrate (CoWoS) interposer, accommodating trace lengths up to 2 mm. The design features 216 data lanes, each operating at 32 Gb/s. For the tested 2-mm trace, the channel insertion loss …
