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.

Abstract: Training a physical interface between a memory device and a memory controller can be performed with an autonomous sweep. The sweep can occur without commands from the host to trigger each parameter sweep. With a two dimensional sweep, instead of interrupting a training mode for a first parameter to sweep a second parameter, circuitry in the memory can automatically sweep the second parameter in the training mode for the first parameter.
