Which of the following memory types is located in the processor chip?

EDO (Extended Data Out) RAM is an older type of dynamic random-access memory used for main system memory modules, not located within the processor chip.

L1 (Level 1) cache is the fastest and smallest cache memory, located directly on the CPU die. It provides immediate access to frequently used data and instructions for the processor, minimizing latency.

xD Picture Card is a type of flash memory card primarily used in digital cameras, it is not a memory type found within a processor chip.

DDR (Double Data Rate) refers to types of synchronous dynamic random-access memory (SDRAM) used for main system memory, typically on RAM modules, not integrated into the processor chip itself.
