TL;DR: It is concluded that natural attenuation of PAHs in polluted river sediments under anaerobic conditions is exceedingly slow, and dredging and biodegradation on land under aerobic conditions would be required to safely remediate and restore polluted sites.

TL;DR: A built in self-diagnosis of EEPROM memory cells, based on threshold voltage extraction, is presented and complementary information is proposed to improve the classical memory diagnosis methodology.
Abstract: Knowing, that the threshold voltage of the EEPROM memory cells is a key parameter to determine the overall performance of the memory, a built in structure to extract this information is a very relevant choice to fast diagnose the failure in the memory. Thus, the objective of this paper is to present a built in self-diagnosis of EEPROM memory cells, based on threshold voltage extraction. In order to extract the threshold voltage, the modified circuit and the associated test sequence are presented. Based on the threshold voltage extraction, complementary information is proposed to improve the classical memory diagnosis methodology.

TL;DR: In this article, a new test structure is proposed to measure the capacitance value of each DRAM cell capacitor in a DRAM array, which has been validated by simulation on a 0.18 /spl mu/m eDRAM technology.
Abstract: The embedded DRAM (eDRAM) is more and more used in system-on-chip (SOC). It is challenging to integrate the DRAM capacitor process into a logic process to get satisfactory yields. The specific process of DRAM capacitor and the low capacitance value (/spl sim/30 fF) of this device induce problems of process monitoring and failure analysis. We propose a new test structure to measure the capacitance value of each DRAM cell capacitor in a DRAM array. This concept has been validated by simulation on a 0.18 /spl mu/m eDRAM technology.
