RAM
🧱 1.RAM definition RAM (Random Access Memory) is the system’s fast, volatile working memory used to hold code and data that the CPU or accelerator needs immediately. It’s measured by capacity, bandwidth, latency, and power; it sits between registers/caches and persistent storage in the memory hierarchy. 🧩 2. Memory Types and Where They’re Used Type Description Use Cases DDR3 Legacy DRAM (240-pin DIMM), 1.5V/1.35V, up to 2133 MT/s Older PCs, embedded systems, legacy servers DDR4 Mainstream DRAM (288-pin DIMM), 1.2V, up to 3200 MT/s Modern desktops, laptops, servers DDR5 Advanced DRAM with PMIC, on-die ECC, up to 8800+ MT/s High-end PCs, AI servers, workstations DDR6 Future DRAM, targeting 8800–17600 MT/s, lower voltage Next-gen AI, HPC, gaming platforms LPDDR4X/5/5X/6 Low-power DRAM...
