A method for reading data from a memory module over a bi-directional bus is provided. The method initiates with issuing a read command. Then, a strobe signal is transitioned from a mid-rail state. In one embodiment, the strobe signal is transitioned to a logical low state. A read enable signal is then transitioned prior to a first falling edge of the strobe signal. The strobe signal represents an earliest availability for valid read data being available. The valid read data is read in response to the read enable signal transition. A microprocessor and a system wherein data is read over a bi-directional bus are included.
