Abstract
A memory controller and a dynamic random access memory (DRAM) interface are disclosed. The memory controller implements signals for the DRAM interface. The DRAM interface includes a differential clock signal, an uncalibrated parallel command bus, and a high-speed, serial address bus. The command bus may be used to initiate communication with the memory device upon power-up and to initiate calibration of the address bus.
