What 4DS Memory works on
In-Memory Computing
In-memory computing does calculations inside or right next to the memory that stores the data, instead of copying the data to a separate processor. It is also called processing-in-memory (PIM) or compute-in-memory.
Memory & Storage
Memory and storage hold the data that processors work on. Memory such as DRAM is fast and loses its contents when power is removed. Storage such as flash (NAND) is slower, cheaper per bit and keeps data without power.
