Techniques and mechanisms for programming an operation mode of a dynamic random access memory (DRAM) device. In an embodiment, a memory controller stores a value in a mode register of a DRAM device, the value specifying whether a per-DRAM addressability (PDA) mode of the DRAM device is enabled. An external contact of the DRAM device is coupled to the memory controller device via a signal line of a data bus. In another embodiment, the memory controller sends a signal to the external contact while the PDA mode of the DRAM device is enabled, the signal to specify whether one or more features of the DRAM device are programmable. |
