Abstract
This device comprises transfer electrodes and read electrodes. The read electrode operates in accordance with two modes. Where it operates based on the charge detection mode, a charge below the read electrode is read out in accordance with the floating gate system, so that a charge detection signal is produced. On the other hand, where it operates based on the charge transfer mode, the read electrode performs a function equivalent to the transfer electrode. This device further comprises selector means, thus permitting the read electrode to select either of two modes to operate in a selected mode.
