Figure 2-16 Submenu “Memory Cache”
The cache memory is a fast intermediate memory located between the CPU
and the main memory (dRAM). If the feature has been enabled, repeated
memory access is not performed in the main memory but in the faster cache
memory. Some hardware or software might require you to disable your cache
memory, because the necessary program execution or waiting times become
too short due to the fast cache memory.
