Abstract
Embodiments of the present invention relate to configurable inputs and/or outputs for memory and memory stacking applications in processor-based systems. More specifically, embodiments of the present invention include processor-based systems with volatile-memory having memory devices that include a die having a circuit configured for enablement by a particular signal, an input pin configured to receive the particular signal, and a path selector configured to selectively designate a signal path to the circuit from the input pin.
Claims19
A processor-based system comprising:
- at least one processor;
- a user interface coupled to the processor;
- a display coupled to the processor;
- at least one communications port coupled to the processor;
- a memory operably coupled to the processor, wherein the processor controls the system by implementing software programs stored in the memory;
- the memory comprising a plurality of dies in a stacked configuration, the die comprising:
- a top surface and a bottom surface separated by a thickness, the die configured to receive a control signal and provide a first path for the control signal disposed through the die from the top surface to the bottom surface in a direction generally parallel to the thickness and a second path disposed through the die from the top surface to the bottom surface in the direction generally parallel to the thickness;
- a circuit included in the die, the circuit configured to be enabled by the control signal via the first path or the second path;
- and
- a path selector comprising a multiplexer to select the first path or the second path for transmission of the control signal.
