Apparatus and method for topography dependent signaling

A method of operation of a first integrated circuit device that communicates with a plurality of other integrated circuit devices, wherein the first integrated circuit device and the plurality of other integrated circuit devices define a system, the method comprising:

• transmitting transmit data onto an external signal line, wherein the transmit data is transmitted in response to an internal transmit signal;
• and
• upon initialization of the system, storing a first value representative of a transmit phase time adjustment that is applied to the internal transmit signal, wherein the first value is determined using information specifying a configuration of the plurality of other integrated circuit memory devices.

An integrated circuit controller device that communicates with a plurality of integrated circuit memory devices, comprising:

• a transmitter circuit to transmit data onto an external signal line at a transmit time that is indicated by an internal transmit signal;
• and
• a first register to store a first value representative of a transmit phase time adjustment that is applied to the transmit time by adjusting a phase of the internal transmit signal, wherein the first value is determined based on information stored in a serial presence detect memory device.

A first integrated circuit device, comprising:

• a means for transmitting transmit data, via an external signal line, to a second integrated circuit device, wherein the transmit data is transmitted from the first integrated circuit device at a transmit time;
• and
• a means for storing a first value representative of a transmit phase time adjustment that is applied to the transmit time such that receive data is sampled substantially centered within a data eye of the receive data by the second integrated circuit device, wherein the first value is determined by polling a supplemental memory device that stores information pertaining to the second integrated circuit device.
