One-shot Garbage Collection for In-memory OLTP through Temporality-aware Version Storage
Anastasia Ailamaki, Periklis Chrysogelos, Angelos Christos Anadiotis, Syed Mohammad Aunn Raza
Most modern in-memory online transaction processing (OLTP) engines rely on multi-version concurrency control (MVCC) to provide data consistency guarantees in the presence of conflicting data accesses. MVCC improves concurrency by generating a new version o ...
ACM2023Perovskite Flash Memory with a Single-Layer Nanofloating Gate
Mohammad Khaja Nazeeruddin, Peng Gao, Hobeom Kim
Here we use triple-cation metal-organic halide perovskite single crystals for the transistor channel of a flash memory device. Moreover, we design and demonstrate a 10 nm thick single-layer nanofloating gate. It consists of a ternary blend of two organic s ...
2020RRAM-VAC: A Variability-Aware Controller for RRAM-based Memory Architectures
David Atienza Alonso, Alexandre Sébastien Julien Levisse, Marco Antonio Rios, Shikhar Tuli
The growing need for connected, smart and energy efficient devices requires them to provide both ultra-low standby power and relatively high computing capabilities when awoken. In this context, emerging resistive memory technologies (RRAM) appear as a prom ...
2020Thermal scanning probe lithography-a review
Jürgen Brugger, Samuel Tobias Howell
Fundamental aspects and state-of-the-art results of thermal scanning probe lithography (t-SPL) are reviewed here. t-SPL is an emerging direct-write nanolithography method with many unique properties which enable original or improved nano-patterning in appl ...
2020TRIAD: creating synergies between memory, disk and log in log structured key-value stores
Rachid Guerraoui, Willy Zwaenepoel, Diego Didona, Oana Maria Balmau
We present TRIAD, a new persistent key-value (KV) store based on Log-Structured Merge (LSM) trees. TRIAD improves LSM KV throughput by reducing the write amplification arising in the maintenance of the LSM tree structure. Although occurring in the backgrou ...
2017Efficient Logging in Non-Volatile Memory by Exploiting Coherency Protocols
James Richard Larus, Nachshon Cohen
Non-volatile memory (NVM) technologies such as PCM, ReRAM and STT-RAM allow processors to directly write values to persistent storage at speeds that are significantly faster than previous durable media such as hard drives or SSDs. Many applications of NVM ...
ACM2017Endurance Management for Resistive Logic-In-Memory Computing Architectures
Giovanni De Micheli, Mathias Soeken, Pierre-Emmanuel Julien Marc Gaillardon
Resistive Random Access Memory (RRAM) is a promising non-volatile memory technology which enables modern in-memory computing architectures. Although RRAMs are known to be superior to conventional memories in many aspects, they suffer from a low writ ...
Ieee2017Imaging and manipulation of skyrmion lattice domains in Cu2OSeO3
Nanoscale chiral skyrmions in noncentrosymmetric helimagnets are promising binary state variables in high-density, low-energy nonvolatile memory. Skyrmions are ubiquitous as an ordered, single-domain lattice phase, which makes it difficult to write informa ...
Amer Inst Physics2016Key/Value-enabled Flash Memory for Complex Scientific Workflows with On-line Analysis and Visualization
Stefan Eilemann, Alessandro Curioni, Peter Morjan, Blake Fitch, Bernard Metzler, Lars Schneidenbach, Ralph Bellofatto, Peter Kaltstein
Scientific workflows are often composed of compute-intensive simulations and data-intensive analysis and visualization, both equally important for productivity. High-performance computers run the compute-intensive phases efficiently, but data-intensive pro ...
Ieee2016Multilevel-cell phase-change memory
In the modern digital era of big data applications, there is an ever-increasing demand for higher memory capacity that is both reliable and cost effective. In the domain of non-volatile memory systems, Flash-based storage devices have dominated the consume ...
