Techopedia Explains Processing In Memory

PIM is primarily designed to eliminate latencies that are visible in standard computer architectures, also known as Von Neumann bottleneck, where memory is only used to store programs and data and the processing is done solely by the processor. PIM framework integrates/embeds a small form factor processor within the memory so that tasks that don’t require extensive processor power can be processed directly within the memory. This helps speed up processing, memory transfer rate, memory bandwidth and decrease processing latency.
