Abstract: The present disclosure relates to a printed circuit board including, a first insulating layer, a first metal layer disposed on the first insulating layer, a bridge disposed on the first metal layer and including a bridge insulating layer and a bridge circuit layer, a second insulating layer disposed on the first insulating layer and covering at least a portion of the bridge, a second metal layer disposed on the second insulating layer, and a connecting via penetrating the bridge and the second insulating layer to connect the first metal layer to the second insulating layer. The connecting via is spaced apart from the bridge circuit layer.

Abstract: A method of operating a memory device includes reading a first page of memory cells containing at least one worn-out memory cell therein using a read voltage, from a first memory block, and reading a second page of memory cells, which extends adjacent to the first page in the first memory block, using the read voltage. An operation is performed to determine a match rate between a position of a column including a “0” bit in the first page with a position of a column including a “0” bit in the second page. Thereafter, the second page is read by adjusting a read pass voltage applied to a word line of another page in the first memory block, when the match rate exceeds a threshold match rate.

Abstract: A display device includes an electronic panel including a first non-folding region, a folding region, and a second non-folding region arranged in a first direction, a support plate disposed under the electronic panel, and a hinge member that defines biaxial rotational axes that are spaced apart from each other in the first direction and that extend in a second direction crossing the first direction. The electronic panel is folded inward or outward about the biaxial rotational axes, and the biaxial rotational axes are defined over or under the support plate depending on a folding direction of the electronic panel.
