摘要:
An AND-type anti-fuse memory cell, and a memory array consisting of AND-type anti-fuse memory cells. Chains of AND type anti-fuse cells are connected in series with each other, and with a bitline contact, in order to minimize the area occupied by the memory array. Each AND type anti-fuse cell includes an access transistor serially connectable to the bitline or the access transistors of other AND type anti-fuse cells, and an anti-fuse device. The channel region of the access transistor is connected to the channel region of the anti-fuse device, and both channel regions are covered by the same wordline. The wordline is driven to a programming voltage level for programming the anti-fuse device, or to a read voltage level for reading the anti-fuse device.
