Abstract
A configuration register used to adjust a clock or request signal with respect to the other. Specifically, a look-up table is provided in the memory controller. The look-up table is filled at bootup such that it contains test information from a master look-up table in the system BIOS, for instance. The look-up table in the memory controller stores current test data correlative to optimal sampling times for the current configuration. Adjustable delay elements or adjustable load elements may be used to change the relative sampling time of the request signal correlative to the values stored in the memory controller look-up table.
