Title: Semiconductor nonvolatile memory and writing method therefor
Inventor: NAKANO KATSUMASA
IPC: G11C17/00
Filed: 1991-07-18
Abstract: PURPOSE:To perform plural times of writing and correction of information to the semiconductor nonvolatile memory by using plural memory elements to be destructed by dissimilar voltage. CONSTITUTION:When the high negative voltage is applied from a writing voltage supply terminal 8 through a bit line 6 to a source electrode 4 of a MOS transistor TR being a 1st memory element 1 and a thin film resistance layer being a 2nd memory element 7, the element 7 is destructed and disconnected first, the potential supply from a voltage Vdd side to the bit line 6 is stopped, and the writing of information to the element 7 is performed. The voltage supplied from the terminal 8 should be kept high enough not to destruct the element 1. To restore the state with the information written to the state of correcting the written information or to the state before writing the information, the MOSTR of the element 1 should be destructed. In short, the negative voltage higher than the voltage which destructs the thin film resistance layer is applied from the terminal 8 through the bit line 6 to the source electrode 4.

Title: Protective circuit
Inventor: NOJIRI KEIKO
IPC: H02H7/00
Filed: 1989-08-03
Abstract: PURPOSE:To interrupt abnormal currents quickly even when a circuit breaker is thrown again by making input currents flow through an amplifier circuit by the blown off small-capacity fuse and tripping the circuit breaker by output currents. CONSTITUTION:When driving current I from a control circuit CTL or a transistor Q2 are made to flow continuously, a small-capacity fuse F2 is blown off in a set time. Since a transistor Q3 is conducted at ground potential through a point C, a resistor R1 and the transistor Q2, the base currents IB of the transistor Q3 are made to flow. Amplified collector currents are made to flow through the trip coil of a none-fuse breaker NFB through the emitter and collector of the transistor Q3 from a point D, and reach a grounding. Currents sufficient for operating the trip coil of the breaker NFB are made to flow instantaneously, and the contact of the breaker NFB is brought to an open state. Even when a circuit breaker 3 again thrown, abnormal currents are interrupted quickly.
