Analyzing the Impact of Process Variations on DRAM Testing Using Border Resistance Traces
نویسندگان
چکیده
As a result of variations in the fabrication process, different memory components are produced with different operational characteristics, a situation that complicates the fault analysis process of manufactured memories. This paper discusses the issue of process variations, and shows how to deal with it in the context of fault analysis and test generation. The paper also introduces the concept of border resistance traces as a tool to optimize test stresses and inspect the impact of process variations on the optimization procedure. The concepts are discussed in the paper with the help of a practical example of a specific defect in the memory.

Concept drift detection in business process logs using deep learning
Process mining provides a bridge between process modeling and analysis on the one hand and data mining on the other hand. Process mining aims at discovering, monitoring, and improving real processes by extracting knowledge from event logs. However, as most business processes change over time (e.g. the effects of new legislation, seasonal effects and etc.), traditional process mining techniques ...

متن کاملMaximizing the Throughput of Cuckoo Hashing in Network Devices
Hash tables form a core component of networkdevices. Because of their large size, they are implemented usingboth fast on-chip SRAM and slow off-chip DRAM. However, thismakes their implementation particularly delicate, as a suboptimalchoice of the hashing scheme parameters may result in a higheraverage query time, and therefore in a lower throughput. Sincehash tables are ...
متن کاملInvestigation of Peak Particle Velocity Variations during Impact Pile Driving Process
Impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. At first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. This is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. It is of high ...
متن کاملImpact of Low-Level-Viremia on HIV-1 Drug-Resistance Evolution among Antiretroviral Treated-Patients
BACKGROUND Drug-resistance mutations (DRAM) are frequently selected in patients with virological failure defined as viral load (pVL) above 500 copies/ml (c/mL), but few resistance data are available at low-level viremia (LLV). Our objective was to determine the emergence and evolution of DRAM during LLV in HIV-1-infected patients while receiving antiretroviral therapy (ART). METHODS Retrospec...
