back-side bus
ATC (Advanced Transfer Cache) bus
Back side bus or cache bus
Execution Trace Cache
Its called the backside bus or cache bus. There's also the ATC bus. Back Side Bus Front side bus or cache bus Back Side Bus
SRAM (Static RAM)
A discrete L2 cache is in the same housing as the processor, but resides on a separate microchip. It typically runs at half the speed of the processor, unlike ATC which resides on the same microchip as the processor and runs at the same speed as the CPU.
The discrete L2 is located within the processor housing, on a separate chip. The Advanced Transfer Cache is located directly on the processor die itself.
atc bus
ram --- Wrong. RAM actually CAN be upgraded without touching the processor. L1, L2, and L3 cache are physically located INSIDE of the processor, so they obviously cannot be changed or upgraded without replacing the processor itself.
L2 cache. Today's processors all have some memory on the processor chip (called a die). Memory on the processor die is called Level 1 cache (L1 cache). Memory in the processor package, but not on the processor die, is called Level 2 cache (L2 cache). Some processors use a third cache farther from the processor core, but still in the processor package, which is called Level 3 cache (L3 cache).
yes..there is a cache which is present in the processor.
