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

Claim 19:
20. The reception method according to claim 11, wherein
the equalizer circuit includes first to Nth (N is an integer of 2 or more) equalizer circuits,
an nth (n is an integer of 1 or more and N or less) decision feedback equalizer is configured to output the output value at each (R+1)th (R is a remainder obtained by dividing a total sample number by N) sampling timing, and
the method further comprises:
detecting, before the data signal is received, an nth inverted tap coefficient that is the tap coefficient at the boundary where the data value of the output value is inverted by changing the tap coefficient in a state in which the second voltage, instead of the voltage of the data signal, is supplied to the nth equalizer circuit; and
setting, at the time of receiving the data signal, the nth inverted tap coefficient to the nth equalizer circuit.
