A disk or memory cache that supports writing. Data normally written to memory or to disk by the CPU is first written into the cache. During idle machine cycles, the data are written from the cache ...
The year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...
Memory takes about 20 times as long to access as the cache on these same CPUs, so even though they only have to go to memory %10 of the time, those accesses take twice the total amount of time that ...

SLC caching tricked me into thinking my SSD was faster than it really is
Your budget SSD only feels fast because a tiny SLC cache is hiding the painfully slow memory chips ...
(1) Solid state storage used as a cache between the computer's main memory (RAM) and a hard drive. The SSD cache holds the data with the most activity, and reading and writing the cache is faster than ...
In the early days of computing, everything ran quite a bit slower than what we see today. This was not only because the computers' central processing units – CPUs – were slow, but also because ...
The gap between the performance of processors, broadly defined, and the performance of DRAM main memory, also broadly defined, has been an issue for at least three decades when the gap really started ...
