It's sometimes called CPU memory or CPU cache memory and is technically a form of random access memory (RAM).

In a simulation test system with 36 cores, 'Jenga' CPU cache memory access increased processing speed by 20 to 30 per cent and energy efficiency by as much as 85 per cent.

The CPU cache is just that, with the L1, L2, and L3 cache acting in unison to hold only the most immediate instructions that a CPU might need.

Researchers at MIT have created a new implementation for how the CPU cache interacts with the processor and data, by replacing the archaic fixed cache found in all modern processors.

AMD introduced its 3D V-Cache technology in 2022, with a new packaging solution that stacks additional layers of cache memory on top of the CPU.

Cache and memory in the many-core era As CPUs gain more cores, resource management becomes a critical performance … ...

L1 cache is extremely small yet fast and is usually built into the processor as CPU cache. This is where recent instructions and data that are likely to be requested are stored.

While it might not be as flashy as a speedy SSD or high-end RAM, the L1, L2, and L3 CPU cache are built into every computer and also have an important job.
