System-level detection and mitigation of DRAM failures offer a variety of system enhancements, such as better reliability, scalability, energy, and performance. Unfortunately …
Scaling down DRAM technology degrades cell reliability due to increased coupling between adjacent DRAM cells, commonly referred to as crosstalk. Moreover, high access frequency …
Bitwise operations are an important component of modern day programming. Many widely- used data structures (eg, bitmap indices in databases) rely on fast bitwise operations on …
DRAM cells in close proximity can fail depending on the data content in neighboring cells. These failures are called data-dependent failures. Detecting and mitigating these failures …
Data compression can be an effective method to achieve higher system performance and energy efficiency in modern data-intensive applications by exploiting redundancy and data …
