What are the design constraints on memory in a PC system?

Design constraints on memory in a PC system include capacity limitations, speed, power consumption, and compatibility with the motherboard and CPU architecture. Memory must fit within the physical space of the system and align with the supported memory types (e.g., DDR4, DDR5). Additionally, performance considerations like latency and bandwidth impact overall system efficiency. Cost is also a critical factor, as higher-performing memory components tend to be more expensive.
