Abstract: A transmission apparatus causes a digital-to-analog conversion unit to perform digital-to-analog conversion on transmission signals pre-equalized by using a compensation filter, then converts electrical signals into optical signals, and outputs the optical signals. A receiving apparatus converts the received optical signals into received electrical signals, then performs analog-to-digital conversion, and demodulates the received signals. A scale estimation unit calculates a slope near an amplitude 0 in a correlation between an amplitude distribution of the pre-equalized transmission signals and an amplitude distribution of the received signals. A scale unit scales amplitude of the received signals on the basis of the calculated slope. A coefficient estimation unit calculates a filter coefficient of the compensation filter on the basis of the pre-equalized transmission signals and the scaled received signals.

Abstract: In a test mode, a comparator compares for each column a value of data read from each memory cell connected to an activated word line with an expected value to be read from each memory cell. An error register holds error data based on a comparison result by a comparator. Each bit of the error data indicates the comparison result by the comparator for a corresponding column. Each bit is set to “0” when the comparison result for the corresponding column always indicates equality whichever word line is activated, and is set to “1” when once the comparison result for the corresponding column indicates difference.
