Abstract
An integrated circuit (IC) memory controller includes receiver circuitry to receive read data from a memory. The receiver circuitry includes equalization circuitry having at least one tap to apply data level equalization to the read data, and a tap weight adapter circuit. The tap weight adapter circuit adaptively generates a data level tap weight corresponding to the data level equalization from an edge analysis of previously received read data.
