Abstract: Systems and methods include receiving data bits at an input pin of a semiconductor device from a host device. The received data is latched in latch circuitries of the semiconductor device that at least partially implements an equalizer to aid in interpreting the received data bits. A first latched bit latched from the first received bit of the received bits is transmitted from the latch circuitries to self-calibration circuitry. The first received bit is also latched in error evaluation circuitry as a second latched bit. The second latched bit is transmitted from the error evaluation circuitry to the self-calibration circuitry. The self-calibration circuitry determines settings for the equalizer without involving the host device in determining the settings after the host device sends the data bits.

Abstract: A decision counter circuit is used in a self-adaptation circuit to apply digital averaging to input signals to obtain adaptive settings of circuit parameters for a memory chip of a memory device during the operation. Individual adaptive settings of the parameters (e.g., impedance, capacitance, equalization parameters) during operation are obtained for each of the memory chips in the memory device. The self-adaptation enables equalization adjustment across temperature and voltage drift.

Abstract: Systems and methods include self-training an equalizer of a semiconductor device using the semiconductor device. The semiconductor device receives an indication of a condition for re-training of the equalizer. The semiconductor device operates the equalizer based on trained values derived during the self-training. The semiconductor device also determines that the condition has been met, and in response, the semiconductor device re-trains the equalizer without invocation of re-training by a host device coupled to the semiconductor device.
