Cache memory is specifically designed to provide high-speed data access to the CPU by storing frequently accessed data and instructions. It acts as a buffer between the CPU and the main memory (RAM), allowing for quicker retrieval of data and enhancing overall system performance. Cache memory stores temporary data that the CPU is actively using, which is crucial for maintaining efficiency during processing tasks.

In contrast, virtual memory is a technique that allows the use of hard drive space to simulate additional RAM, thus providing the appearance of a larger memory size than what is physically available. Secondary memory refers to storage devices like hard drives or SSDs where data is stored permanently, not for immediate processing. ROM (Read-Only Memory) is a type of non-volatile memory that contains permanent data such as firmware, and it is not involved in temporary data storage for the CPU. The unique function of cache memory in facilitating quick access to data currently in use sets it apart as the correct answer in this context.
