Figure 6-4 “Memory Cache” Menu
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
the 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.
[Disabled] Cache is disabled
[Write Through] Write access is not concluded until the entry has been made in main
memory
[Write Back] Write access is concluded immediately; the entry in main memory
takes place in the backround (default)
