ABSTRACT:
A solid-state image pickup device includes a light receiving cell for accumulating electric charges created in response to a photo energy striking the gate of an amplification-type sensor and then produces a signal from the source region based on the accumulated carriers, a memory cell including an amplification-type memory cell having the same type as that of the abovementioned amplification-type sensor, to accumulate a signal transferred from the light receiving cell into the base region of the amplification-type memory cell, and a signal line for electrically connecting the source region of the light receiving cell and the source region of the memory cell. The shift of the accumulation start timing to each row of the light receiving cells is suppressed to a small value. The same signal can be read from the memory cell several times.
