Limitations of Partial Compaction: Towards Practical Bounds

Nachshon Cohen

Compaction of a managed heap is a costly operation to be avoided as much as possible in commercial runtimes. Instead, partial compaction is often used to defragment parts of the heap and avoid space blowup. Previous study of compaction limitation provided ...

A Fully-Digital Spectrum Shaping Signaling for Serial-Data Transceiver with Crosstalk and ISI Reduction Property in Multi-Drop Memory Interfaces

Seyed Armin Tajalli, Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust

An efficient signaling scheme for serial-data transceivers (TRXs) has been proposed, which can properly reduce inter-symbol interference (ISI) and crosstalk (Xtalk) in memory interfaces. The proposed architecture relies on fully-digital implementation rath ...

Multilevel-Cell Phase-Change Memory: A Viable Technology

Milos Stanisavljevic, Aravinthan Athmanathan, Evangelos Eleftheriou

In order for any non-volatile memory (NVM) to be considered a viable technology, its reliability should be verified at the array level. In particular, properties such as high endurance and at least moderate data retention are considered essential. Phase-ch ...

Advances in digital SiPMs and their application in biomedical imaging

Edoardo Charbon

Similar to analog silicon photomultipliers (SiPMs), digital SiPMs (dSiPMs) essentially consist of an array of single-photon avalanche photodiodes (SPADs). Instead of a passive quench resistor, however, an active quenching circuit is locally integrated with ...

Libra: Software-Controlled Cell Bit-Density to Balance Wear in NAND Flash

Paolo Ienne, Xavier Jimenez, David Novo Bruna

Hybrid flash storages combine a small Single-Level Cell (SLC) partition with a large Multilevel Cell (MLC) partition. Compared to MLC-only solutions, the SLC partition exploits fast and short local write updates, while the MLC part brings large capacity. O ...

A (Nearly) Free Lunch : Extending NAND Flash Lifetime by Exploiting Neglected Physical Properties

Xavier Jimenez

NAND flash is a key storage technology in modern computing systems. Without it, many devices would probably not exist today or would at least not benefit from as many features. The very large success of this technology motivated massive efforts to scale it ...

Flash-aware Database Transactions

Radu Ioan Stoica

Over the past 40 years, hard disks, the traditional building block of storage systems, have become increasingly slower when compared to the other system components such as the main memory and the CPU. Hard disks face mechanical constraints that cause their ...

BF-Tree: Approximate Tree Indexing

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis

The increasing volume of time-based generated data and the shift in storage technologies suggest that we might need to reconsider indexing. Several workloads - like social and service monitoring - often include attributes with implicit clustering because o ...
