ABSTRACT:
A method and data receiver apparatus implement a high speed, such as double data rate (DDR), memory read data eye stretcher and a design structure on which the subject circuit resides is provided. Altering the reference level is performed to increase the size of the data eye. Knowledge of the previous data state is used to adjust the reference level for the current data being latched so that the data eye is maximized.
