Selective Plasma Mode Modulation in HfO₂ Charge Trap Layers via RP/DP/RP Atomic Layer Deposition for Enhanced Memory Performance and Interface Quality

Micromachines
Hafnium oxide (HfO2) has emerged as a promising charge trap layer (CTL) for nonvolatile memory devices; however, its long-term reliability remains challenging due to leakage current through grain boundary pathways and interface defect formation.

Systematic Analysis of Spacer and Gate Length Scaling on Memory Characteristics in 3D NAND Flash Memory

Applied Sciences
This study investigates the impact of oxide/nitride (ON) pitch scaling on the memory performance of 3D NAND flash memory. We aim to enhance 3D NAND flash memory by systematically reducing the spacer length (Ls) and gate length (Lg) to achieve improved ...

Memory Window in Ferroelectric Field-Effect Transistors: Analytical Approach [PDF]

, 2022
A memory window of ferroelectric field-effect transistors (FeFETs), defined as a separation of the HIGH-state and the LOW-state threshold voltages, is an important measure of the FeFET memory characteristics.

CCR5 closes the temporal window for memory linking

Nature, 2022
Real-world memories are formed in a particular context and are often not acquired or recalled in isolation1-5. Time is a key variable in the organization of memories, as events that are experienced close in time are more likely to be meaningfully associated, whereas those that are experienced with a longer interval are not1-4.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
