Abstract
In a general aspect, a circuit can include a printed circuit board having an opening defined therein and an electrical write line disposed on the circuit board. The electrical write line can be connected to a semiconductor memory device, and be configured to transmit a write voltage signal to the semiconductor memory device to write data therein in a write mode of the circuit. The circuit can also include an input voltage terminal disposed on the circuit board. The input voltage terminal can be configured to receive a write-protection voltage. The circuit can also include a reversible closing element that, when inserted in the opening in the circuit board, electrically connects the electrical write line and the input voltage terminal to pass the write- protection voltage to the electrical write line connected to the semiconductor memory device to reversibly enable a write-protect mode of the circuit.
