Critical Memory Performance Metrics for DDR4 Systems: Data Bus Utilization Analysis
This is the heart of any Server memory subsystem performance measurement. How much data can be passed within a second. Data bus utilization's can be expressed as rates (MB per Sec) or as percentages indicating utilization (used cycles divided by ...
Critical Memory Performance Metrics for DDR4 Systems
Second only to the speed of the processor, memory subsystems design dominates a server’s performance. The three traditional metrics of Latency, Bandwidth and Power Management are no longer enough to categorize the performance of modern Server memory ...
Data Center Down Time: DRAM Row Hammer Failures in the field
DDR3 memory is at the heart of almost all cloud computing servers today. A recently publicized failure mechanism in DDR3 memory, coined Row Hammer, has been shown to not only be a reliability issue but also a security risk for servers, laptops, ...
