ACache Memories
BPrimary Memories as the primary storage medium
CVirtual Memories
DFlash Memories
Answer:
D. Flash Memories
Read Explanation:
An SSD (Solid State Drive) consists of a set of flash memory chips (specifically NAND flash memory). Unlike traditional Hard Disk Drives (HDDs), which rely on spinning magnetic platters and moving read/write heads, an SSD has no moving mechanical parts. Key Internal Components of an SSD NAND Flash Memory Chips: The primary storage medium where data is stored persistently (retained even when power is turned off) in arrays of floating-gate or charge-trap transistors. Controller: The embedded processor that manages data placement, read/write operations, error correction (ECC), wear leveling, and communication with the host computer. DRAM (Cache): A small amount of fast volatile memory used to cache mapping tables and frequently accessed data to speed up performance (found in most high-performance SSDs, though some budget drives are "DRAM-less"). Host Interface: The physical connection and protocol used to transfer data to the motherboard (e.g., SATA, NVMe over PCIe).
