Integrated circuit device having programmable input capacitance
Abstract:
An embodiment is directed to an integrated circuit device having programmable input capacitance. For example, a programmable register of a memory device may store a value representative of an adjustment to the input capacitance value of a control pin. An embodiment is directed to controlling the skew of a synchronous memory system by allowing programmability of the lighter loaded pins in order to increase their load to match the more heavily loaded pins. By matching lighter loaded pins to more heavily loaded pins, the system exhibits improved synchronization of propagation delays of the control and address pins. In addition, an embodiment provides the ability to vary the loading depending on how many ranks are on the device.
