Abstract: The present invention relates to bit cell arrays of read-only-memories, and more specifically, to a bit cell array capable of preventing a coupling effect between adjacent bit lines. In addition, the bit cell array according to the present invention does not require an additional device in order to prevent the coupling effect. In accordance with the present invention, the bit cell array comprising: a plurality of bit lines arranged in a row in a first direction; a plurality of ground lines in a row in a second direction vertical to the first direction; a plurality of word lines arranged with a zigzag line with respect to the second direction; and a plurality of ROM bit cells partially formed at a cross-section point of the bit lines and the word lines. In the meanwhile, the ROM bit cells are arranged with a zigzag line with respect to adjacent bit lines. Additionally, the ROM bit cells comprise a drain terminal, a gate terminal and a source terminal.
