    Which volatile memory provides the fastest on-chip storage for the CPU?

    ক)
    SRAM (registers and caches)
    খ)
    DRAM
    গ)
    NAND
    ঘ)
    NOR Flash

    Explanation

    SRAM uses cross-coupled inverters for stable, fast storage without refresh. It’s larger per bit than DRAM, so used for registers and caches. DRAM scales denser but slower and needs refresh. Flash is non-volatile and much slower for writes.
