Virtual Coset Coding for Encrypted Non-Volatile Memories with Multi-Level Cells
Stephen Longofono, Seyed Mohammad Seyedzadeh, Alex K. Jones
PCM is a popular backing memory for DRAM main memory in tiered memory systems. PCM has asymmetric access energy; writes dominate reads. MLC asymmetry can vary by an order of magnit…

Mitigating Wordline Crosstalk using Adaptive Trees of Counters
Seyed Mohammad Seyedzadeh, Alex K. Jones, Rami Melhem
High access frequency of certain rows in the DRAM may cause data loss in cells of physically adjacent rows due to crosstalk. The malicious exploit of this crosstalk by repeatedly a…

Enabling Fine-Grain Restricted Coset Coding Through Word-Level Compression for PCM
Seyed Mohammad Seyedzadeh, Alex K. Jones, Rami Melhem
Phase change memory (PCM) has recently emerged as a promising technology to meet the fast growing demand for large capacity memory in computer systems, replacing DRAM that is imped…
