For instance, DRAM memory access typically takes 20 to 80 nanoseconds (billionths of a second), but CPU arithmetic operations may take only a nanosecond or less. There are several ways in which this disparity is handled. CPUs have a small number of registers, very fast SRAM that hold current instructions and the data on which they operate.
