Which of the following defines memory interleaving?

The L1 cache is an on-die processor cache and is entirely separate from the DIMM-level interleaving mechanism, which operates only within main system memory.

Memory interleaving works by spreading sequential memory addresses across multiple physical DIMM modules within one bank, so the memory controller can pipeline read and write operations - accessing the next module while the previous one is still completing its cycle - which reduces latency and increases overall memory throughput.

The processor is not a target in memory interleaving; the technique distributes data among memory modules in a bank, not between DIMMs and the CPU itself.

The L2 cache, like L1, is a processor or chipset-level cache and is not involved in memory interleaving, which is purely a main memory controller function.
