Critical Memory Performance Metrics for DDR4 Systems: Power Management
If you are Facebook and its 3 am on the East Coast of the United States you probably want to see your Servers in a low power state. This can save you money and make your server farms more ‘green’.
Critical Memory Performance Metrics for DDR4 Systems: Latency
There are two types of latency to consider when looking at the cycle by cycle transmission of data on the DDR4 Data Bus. The first is the time between the Read or Write command and the data associated with that command, refered to as CAS and CAS ...
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, ...
