Abstract: Decision feedback equalization (DFE) training time in a memory device is reduced through the use of a hybrid search to select values of tap coefficients for taps in the DFE. The hybrid search includes two searches. A first search is performed to identify initial values of tap coefficients, a second search uses the initial values of tap coefficients to find the final values of tap coefficients.
