ABSTRACT:
Systems, methods and devices for equalization include a first adaptive equalizer to process read data or write data to respectively produce equalized read data or write data; a first detector to detect the equalized read data or the equalized write data to respectively produce detected read data or detected write data; a first comparator to determine an adjustment input based on a comparison of the equalized read data to the detected read data, or the equalized write data to the detected write data; and a second adaptive equalizer to process refined equalized read data or refined equalized write data to respectively produce twice equalized read data or twice equalized write data. The refined equalized read data or the refined equalized write data is respectively produced based on (i) the equalized read data and the adjustment input or (ii) the equalized write data and the adjustment input.
