Assignee: KIOXIA CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A reception device configured to receive a data signal representing a data value 0 or 1, the reception device comprising:
an equalizer circuit configured to output an output value representing a result obtained by comparing a voltage based on the received data signal and a first voltage as a reference, at each clock timing corresponding to the data signal; and
a control circuit connected to the equalizer circuit,
the control circuit being configured to:
change, before the data signal is received, a tap coefficient related to a characteristic of the equalizer circuit in a state in which a second voltage different from the first voltage, instead of the voltage of the data signal, is supplied to the equalizer circuit, to detect an inverted tap coefficient that is the tap coefficient at a boundary where a data value of the output value is inverted; and
set, at a time of receiving the data signal, the inverted tap coefficient to the equalizer circuit.
