Abstract
An embodiment non-volatile memory device includes an array of memory cells arranged in rows and columns; a plurality of local bitlines; and a plurality of main bitlines, each main bitline being coupleable to a corresponding subset of local bitlines. The memory cells of each column are coupled to a corresponding local bitline. The memory device further includes a column decoder, which can be controlled electronically so as to couple each main bitline to a selected local bitline of the corresponding subset of local bitlines. The column decoder couples each main bitline to two different points of the corresponding selected local bitline.
