System memory accelerators are specialized hardware and software components that are designed to increase the performance of a system's memory subsystem. They include caching hardware and software, hardware or software that reduce memory latency, memory scrubbing, and memory deduplication. Caching is a technique used to increase a system's memory performance by storing recently used data in a faster and smaller memory area. This allows for faster retrieval of data and a reduction in memory latency when the data is needed again. Memory scrubbing is the process of identifying, removing, and re-allocating damaged memory cells on a system's DRAM, to improve performance and reliability. Memory deduplication is a process of removing redundant data from a system's memory, resulting in reduced storage requirements and improved memory access times.
