Non-volatile main memory management methods based on a file system

ABSTRACT There are upcoming non-volatile (NV) memory technologies that provide byte addressability and high performance. PCM, MRAM, and STT-RAM are such examples. Such NV memory can be used as storage because of its data persistency without power supply while it can be used as main memory because of its high performance that matches up with DRAM. There are a number of researches that investigat...

Securing Non-Volatile Main Memory

Non-volatile memories provide energy efficiency, tolerance against power failure, and “instant-on” power-up. These memories are likely to replace traditional volatile memory in next-generation laptops and desktops. However, the move to non-volatile memory introduces new vulnerabilities; sensitive data such as passwords and keys residing in main memory persists across reboots and can be probed d...

NOVA: A Log-structured File System for Hybrid Volatile/Non-volatile Main Memories

Fast non-volatile memories (NVMs) will soon appear on the processor memory bus alongside DRAM. The resulting hybrid memory systems will provide software with submicrosecond, high-bandwidth access to persistent data, but managing, accessing, and maintaining consistency for data stored in NVM raises a host of challenges. Existing file systems built for spinning or solid-state disks introduce soft...

Log-Structured Non-Volatile Main Memory

Emerging non-volatile main memory (NVMM) unlocks the performance potential of applications by storing persistent data in the main memory. Such applications require a lightweight persistent transactional memory (PTM) system, instead of a heavyweight filesystem or database, to have fast access to data. In a PTM system, the memory usage, both capacity and bandwidth, plays a key role in dictating p...
