SDRAM Latency

SDRAM latency refers to delays in transmitting data between the CPU and SDRAM. SDRAM latency is often measured in memory bus clock cycles. However, the CPU operates faster than the memory, so it must wait while the proper segment of memory is located and read, before the data can be sent back. This also adds to the total SDRAM latency.
