Semiconductor readout circuit |
摘要 |
A semiconductor readout circuit reads out a potential of each of plural data lines by comparing the potential with a potential of a common reference data line, using a sense amplifier provided for each of the data lines. This semiconductor readout circuit has a current control circuit provided for each of the data lines. The current control circuit controls the potential of the corresponding one of the data lines so that a potential difference between the potential of the corresponding data line and the potential of the reference data line can be reduced based on an output as to the potential difference detected by the sense amplifier.
