L3 Cache
There is no specific name for memory caches based on physical location. CPU memory caches are named for function, not location.
As such, there are Level 1, Level 2, and Level 3 caches (and, theoretically, there's nothing preventing Levels 4 and up from being created). Each can be located anywhere (on-die, in-package, off-chip, etc.) depending on the design of the CPU and motherboard.
Modern x86 chips from Intel and AMD include up to L3 cache on-die.
