Abstract: Methods, systems, and devices for receiver decision feedback equalization calibration are described. A memory system may support implementing respective decision feedback equalization (DFE) values at respective receivers using interpolation logic.

The interpolation logic may output the voltage values via a serial bus to each receiver, and each receiver may apply, to respectively received data, a DFE value corresponding to a respectively received voltage value.

Abstract: Methods, systems, and devices for data alignment for memory are described. A memory device may implement individual time adjustments to align portions of a multilevel signal modulated by a modulation scheme with three levels. In some cases, signal paths for generating and transmitting the portions of the multilevel signal may reference a clock signal, and adjustable delay circuits may apply individual delays to the clock signal received at each signal path. For example, a first adjustable delay circuit may apply a first time adjustment to the clock signal received at a first signal path for generating a first portion. And, a second adjustable delay circuit may apply a second time adjustment to the clock signal received at a second signal path for generating a second portion. Applying the time adjustments to the signal paths may align the portions of the multilevel signal in time, compared to the clock signal.

As part of a low-speed testing phase of a memory system, a low-speed tester may measure the change in phase of a set of clock signals in response to a change in a configuration of the memory system. For example, the low-speed tester may communicate with a mimic circuit of the memory system to determine a first frequency of a first clock signal of the multi-phase clock associated with a first configuration of the memory system and determine a second frequency of the first clock signal associated with a second configuration of the memory system. The low-speed tester may store an indication of the difference between the first frequency and the second frequency, and a high-speed tester may use the difference as part of selecting a set of trim parameters for the multi-phase clock signal.
