摘要:
A non-volatile memory cell and method for reading it are disclosed. In one embodiment, the non-volatile memory cell includes a fuse with a first terminal coupled to a first power supply voltage terminal, and a second terminal, a first transistor having a first current electrode coupled to the second terminal of the programmable fuse, a second current electrode, and a control electrode, and a second transistor having a first current electrode connected to the first power supply voltage terminal, a control electrode coupled to the control electrode of the first transistor, and a second current electrode coupled to the control electrode. By applying a read signal to the control electrode of the first transistor, the state of the cell (blown or unblown) is read.
