Unified Memory is a computer architecture design where the central processing unit (CPU) and graphics processing unit (GPU) share the same pool of memory. Instead of each component having its own separate memory, both access a single, unified memory space. This allows for faster data sharing, reduces duplication, and increases efficiency in tasks that require both processing and graphics power. Unified Memory is commonly used in modern systems to improve performance and simplify programming, especially in applications like gaming, scientific computing, and artificial intelligence.
