Abstract: A memory circuit includes an array including a plurality of memory cells arranged across a plurality of columns and a plurality of voltage control circuits, each of the plurality of voltage control circuits operatively coupled to the memory cells of a corresponding one of the plurality of columns. Each of the plurality of voltage control circuits includes a first portion configured to provide a first voltage drop in coupling a supply voltage to the memory cells of the corresponding column and a second portion configured to provide a second voltage drop in coupling the supply voltage to the memory cells of the corresponding column. The first voltage drop is substantially smaller than the second voltage drop.

Abstract: A lens assembly module is provided and includes: a plurality of lenses, a lens barrel disposed around the lens and including an incident end, where light from the object enters the lens barrel, and an emergent end, where light from the object exits the lens barrel; and a first light shielding film disposed in a mounting recess, which is defined by a surface of one of the lenses closest to the emergent end and is adjacent to a circumference of the lens closest to the emergent end.
