There are two kinds of volatile RAM: dynamic and static. Even though both types need continuous electrical current to retain data, there are some important differences between them. Dynamic RAM (DRAM) is very popular due to its cost-effectiveness. DRAM stores each bit of information in a different capacitor within the integrated circuit. DRAM chips need just one single capacitor and one transistor to store each bit of information. This makes it space-efficient and in… Witryna20 wrz 2024 · Although the processor does not reorder un-cacheable memory accesses, un-cacheable variables must be marked as volatile to guarantee that the compiler does not reorder the memory accesses.
