Field
"Memory cache" in the main menu:
Figure 6-4
A cache is a fast memory buffer between the CPU and main memory
(DRAM). Recurrent memory access operations are executed in the fast
cache, instead of main memory, if the function is enabled. In rare
instances involving some hardware and software combinations, it may
be necessary to disable the cache because the program runtimes or
waits are too short on account of the fast cache.
