1. A method for dynamically estimating interference compensation thresholds of a page of memory comprising:
computing a histogram and a corresponding threshold based on a plurality of interference states of an interference source;
clustering the plurality of interference states to determine an effective number of interference states; and
estimating a read threshold to dynamically compensate an interference noise associated with each interference state of the effective number of interference states of the target row based on the histogram.
