Dual-mode photosensitive pixel with gain stage
A photosensitive pixel with gain stage is disclosed. The photosensitive pixel with gain stage may receive an input light stimulus and output a corresponding output voltage in response to the input light stimulus. The output voltage may correspond linearly to the magnitude of the input light stimulus over a linear operating region and logarithmically to the magnitude of the input light stimulus over a logarithmic operating region. In this manner, the photosensitive pixel with gain stage may be both sensitive to input light stimuli over the linear operating region and may exhibit dynamic range enabling non-saturated response to input light stimuli over the logarithmic operating region. |

Read performance of a non-volatile memory device, in particular a non-volatile memory device with buried selection transistor
The non-volatile memory device comprises memory cells each comprising a selectable state transistor having a floating gate and a control gate. The state transistor is of the depletion-mode type and is advantageously configured so as to have a threshold voltage that is preferably negative when the memory cell is in a virgin state. When the memory cell is read, a read voltage of zero may then be applied to the control gate and also to the control gates of the state transistors of all the memory cells of the memory device. |

Semiconductor device including gate electrode extending between nanosheets
A semiconductor device according to example embodiments of inventive concepts may include a substrate, source/drain regions extending perpendicular to an upper surface of the substrate, a plurality of nanosheets on the substrate and separated from each other, and a gate electrode and a gate insulating layer on the substrate. The nanosheets define channel regions that extend in a first direction between the source/drain regions. The gate electrode surrounds the nanosheets and extends in a second direction intersecting the first direction. The gate insulating layer is between the nanosheets and the gate electrode. A length of the gate electrode in the first direction may be greater than a space between adjacent nanosheets among the nanosheets. |
