DRAM-less SSDs used to be terrible—HMB changed everything ...

In this paper, the authors analyze the trade-offs in architecting stacked DRAM either as part of main memory or as a hardware-managed cache. Using stacked DRAM as part of main memory increases the ...

The new Intel “Knights Landing” processor’s topology includes what it calls near memory, an up to 16 GB block of on-package memory accessible faster and with higher bandwidth than traditional main ...

Cache memory significantly reduces time and power consumption for memory access in systems-on-chip. Technologies like AMBA protocols facilitate cache coherence and efficient data management across CPU ...

Modern multimedia applications have been appearing and developing in the marketplace at an increasingly rapid pace. Used in applications such as handheld personal digital assistants, cellular phones, ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...

In a computer, the entire memory can be separated into different levels based on access time and capacity. Figure 1 shows different levels in the memory hierarchy. Smaller and faster memories are kept ...

The dynamic interplay between processor speed and memory access times has rendered cache performance a critical determinant of computing efficiency. As modern systems increasingly rely on hierarchical ...

The disk cache in OS X can sometimes use a fair amount of the system's RAM, and clearing it can help you figure out how much RAM your applications and system processes are using. Topher, an avid Mac ...

Editor’s Note: Demand for increasing functionality and performance in systems designs continues to drive the need for more memory even as hardware engineers balance the dynamics of system capability, ...
