Synchronous DRAM (SDRAM) has become a mainstream memory of choice in embedded system memory design due to its speed, burst access and pipeline features. For high-end applications using processors such as Motorola MPC 8260 or Intel StrongArm, the interface to the SDRAM is supported by the processor’s built-in peripheral module.
