In computational complexity, a field of theoretical computer science, random-access Turing machines extend the functionality of conventional Turing machines by introducing the capability for random access to memory positions. The inherent ability of RATMs to access any memory cell in a constant amount of time significantly decreases the computation time required for problems where data size and access speed are critical factors.^[1] As conventional Turing machines can only access data sequentially, the capabilities of RATMs are more closely with the memory access patterns of modern computing systems and provide a more realistic framework for analyzing algorithms that handle the complexities of large-scale data.^[2]
