Memory Cache
Enabling
cache
saves time for the CPU by holding data most recently accessed in regular
memory (dynamic RAM or DRAM) in a special storage area of static RAM (SRAM), which is
faster. Before accessing regular memory, the CPU first accesses the cache. If it does not find
the data it is looking for there, it accesses regular memory. Selecting "Memory Cache" from the
Main menu displays a menu like the one shown here. The actual features displayed depend on
your system's hardware.
