Abstract
A non-volatile memory device which enables use of a folded bit line system includes odd and even main bit lines, a plurality of sub-bit lines connected to the main bit lines through selection gates. Conductive and non-conductive states of the selection gate connecting to the odd main bit line and the selection gate connecting to the even main bit line are controlled by different selection signal lines so that the odd main bit line and the even bit line are operated selectively.
