Impact of the precursor chemistry and process conditions on the cell-to-cell variability in 1T-1R based HfO RRAM devices.

The Resistive RAM (RRAM) technology is currently in a level of maturity that calls for its integration into CMOS compatible memory arrays. This CMOS integration requires a perfect understanding of the cells performance and reliability in relation to the deposition processes used for their manufacturing. In this paper, the impact of the precursor chemistries and process conditions on the performance of HfO based memristive cells is studied.

Material insights of HfO2-based integrated 1-transistor-1-resistor resistive random access memory devices processed by batch atomic layer deposition.

With the continuous scaling of resistive random access memory (RRAM) devices, in-depth understanding of the physical mechanism and the material issues, particularly by directly studying integrated cells, become more and more important to further improve the device performances. In this work, HfO2-based integrated 1-transistor-1-resistor (1T1R) RRAM devices were processed in a standard 0.25 μm complementary-metal-oxide-semiconductor (CMOS) process line, using a batch atomic layer deposition (ALD) tool, which is particularly designed for mass production.

The optimal treatment of severe hypertension in pregnancy: update of the role of nicardipine.

Objective: Hypertensive disorders in pregnancy remain a major cause of maternal morbidity and mortality. Blood pressure control is essential for maternal and neonatal outcome. Therefore, we analyzed the potency and side effects of two treatment options (nicardipine compared to labetalol) in order to gain insight in improved treatment of severe hypertension during pregnancy and to evaluate the feasibility of a randomised controlled trial.

[Metformin, renal function and lactate: the MetClear Study].

Objective: To map the relation between metformin prescription and renal function in an outpatient setting. To investigate whether there is an association between renal function, metformin concentration and lactate concentration.

Design: Pilot for a prospective observational cohort study.
