In this paper key design issues and considerations of a low-cost 3-D Cu-TSV technology are investigated. The impact TSV on BEOL interconnect reliability is limited, no failures have been observed. stress MOS devices causes <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">${\rm Vth}$</tex></formula> shifts, further analysis required to understand their importance.

An ever increasing number of dynamic interactive applications are implemented on portable consumer electronics. Designers depend largely operating systems to map these the architecture. However, today's embedded abstract away precise architectural details platform. As a consequence, they cannot exploit energy efficiency scratchpad memories. We present in this paper novel integrated hardware/software solution support memories at high abstraction level. hardware alleviate transfer cost from/to...
As scaling becomes increasingly difficult, 3D integration has emerged as a viable alternative to achieve the requisite bandwidth and power efficiency challenges. However mechanical stress induced by through silicon vias (TSV) is one of key constraints in flow that must be controlled order preserve integrity front end devices. For first time an extended comprehensive study given for single- arrayed TSVs its impact on both analog digital FEOL devices circuits. This work provides complete...
This paper addresses the problem of mapping an application, which is highly dynamic in future, onto aheterogeneous multiprocessor platform energy efficient way. A two-phase scheduling method used for that purpose. By exploring Pareto curves and scenarios generated at design time, run-time scheduler can easily find a good very low overhead, satisfying system constraints minimizing consumption. real-life example from 3D quality service kernel to show effectiveness our method.
The power density inside high performance systems continues to rise with every process technology generation, thereby increasing the operating temperature and creating "hot spots" on die. As a result, performance, reliability consumption of system degrade. To avoid these spots", "temperature-aware" design has become must. For low-power embedded though, it is not clear whether similar thermal problems occur. These have very different characteristics from ones: they consume hundred times less...
Stacking memory with 3D chip integration technology could provide the much needed bandwidth and density for mobile applications at low power. The contribution of this paper is to review desired attributes a stackable from system aspects discuss its implementation challenges.
Microglia exhibit diverse morphologies reflecting environmental conditions, maturity or functional states. Thus, morphological characterization provides important information to understand microglial roles and functions. Most recent analysis relies on classifying cells based parameters. However, this classification may lack biological relevance, as represent a continuum rather than distinct, separate groups, do not correspond mathematically defined, clusters irrelevant of function. Instead,...
Interactions among brain areas are essential to most cognitive functions. Neuronal interactions between these depend on the modulation of synaptic strength. However, this remains poorly understood. We recorded evoked responses at four hippocampal pathways in freely moving male rats across 24 hours. show that strength oscillates with a very slow periodicity and correlates durations vigilance states. A model based hypnogram data one pathway was able predict evolution pathways, except one....
Convergence of communication, consumer applications and computing within mobile systems pushes memory requirements both in terms size, bandwidth power consumption. The existing solution for the bottle-neck is to increase amount on-chip memory. However, this becoming prohibitively expensive, allowing 3D stacked DRAM become an interesting alternative applications. In paper, we examine power/performance benefits three different scenarios. Our high-level Through Silicon Via (TSV) models have...

As a result, performance, reliability consumption of system degrade. To avoid these spots', 'temperature-aware' design has become must.

Silicon substrates can be strategically isolated or unified among tiers in a through-silicon-via (TSV)-based 3-D integrated circuit (IC) structure, for the suppression of intertier substrate noise coupling reduction grounding impedance silicon as whole, respectively. A two-tier IC demonstrator 130-nm CMOS technology was successfully tested and analyzed with respect to intra coupling. Each tier stack includes digital source circuits (NSs) monitors, embodies in-place measurements An equivalent...
Abstract The superiority of spaced over massed learning is an established fact in the formation long-term memories (LTM). Here we addressed cellular processes and temporal demands this phenomenon using a weak spatial object recognition (wSOR) training, which induces short-term (STM) but not LTM. We observed SOR-LTM promotion when two identical wSOR training sessions were by inter-trial interval (ITI) ranging from 15 min to 7 h, consistently with training. promoting effect was dependent on...
Besides the stress around Cu TSV's, also induced by microbumps is a main contributor to transistor level stress.
