Abstract
A flash memory device includes a flash cell array, a first flash fuse cell fusing circuit, a second flash fuse cell fusing circuit, a third flash fuse cell fusing circuit and a plurality of fuse sense amplifying circuits. The first, second and third flash fuse cell fusing circuits all share bit lines with a flash cell array and have flash fuse cells. The first flash fuse cell fusing circuit may be used to control a connection between the flash cell array and an external logic circuit. The second flash fuse cell fusing circuit may be used to change an address of a defective cell into an address of a redundancy cell. The third flash fuse cell fusing circuit may be used to control a DC level for adjusting a reference value used in a manufacturing process of the flash memory device. The fuse sense amplifying circuits are coupled to the bit lines to read data from the bit lines, respectively.
