    摘要: In a semiconductor wafer (1), an internal circuit such as a ROM formed at a product region or a chip (2) can be tested via a test pad (5) formed on a scribe line (3). Here, since the test pad (5) is formed on the scribe line (3), after the semiconductor wafer has been once cut off and separated away from each other as chips along the scribe lines (3), respectively, since the test pads (5) are all broken off, ROM test will not be executed again. In other words, since the test conditions of the product test of the separated chip (2) cannot be decoded or deciphered by another person, it is possible to provide a semiconductor device of high secrecy, which can be preferably used as an IC card.

    摘要: A plurality of erase circuits are provided for the blocks BLK(0) to BLK(n), each for one block. Protect circuits are connected to the erase circuits, respectively. The protects circuits generate protect signals PROT0 to PROTn, respectively. Each protect signal indicates whether the protect circuit is set in protect mode or not. Each erase circuit receives the protect signal from the protect circuit connected to it. A unit provided in the erase circuit determines, from the protect signal, whether the protect circuit is set in the protect mode. The unit changes the voltage applied to the sources of the memory cells of the cell block connected to the erase circuit, in accordance with whether the protect circuit is set in the protect mode or not. When a voltage is applied to the sources of the memory cells, a data item of a logic value is read from each memory cell. When a different voltage is applied to the sources of the memory cells, a data item of the other logic value is read from each memory cell. Hence, whether or not the protect circuits are set in protect mode can be determined, without erasing or writing data in the block of the memory cell array.

    摘要: A comparator compares data read out by a sensing amplifier with input data, and outputs equality data when both of the data are equal to each other, while the comparator outputs inequality data when both of the data are not equal to each other. When the comparator outputs inequality data for at least one time within a predetermined period decided by a control signal, the latch circuit latches and keeps outputting the inequality data. The latch circuit latches and outputs equality data when the comparator continuously outputs equality data within the period. Within the period decided by the control signal, the determination circuit determines whether or not writing has been completed on the basis of output data of the latch circuit. The re-write signal generator circuit sends a re-write signal to a write circuit when the determination circuit determines that writing is not yet completed.

    摘要: Source and drain regions of a second conductivity type are formed in a stripe form in the surface area of a semiconductor substrate of a first conductivity type. A first insulation film is formed on the source and drain regions of the substrate. A second thin insulation film having a tunnel effect is formed on that part of the substrate which lies between the source and drain regions. A floating gate is formed on the second insulation film. A third insulation film is formed on the first insulation film, the floating gate and that part of the substrate which lies between the source and drain regions and on which the second insulation film is not formed. A control gate is formed on the third insulation film in a stripe form extending in a direction which intersects the source and drain regions. An impurity region of the first conductivity type having an impurity concentration higher than the substrate is formed in the substrate except the source and drain regions and the portions lying below the control gate. A floating gate transistor is constituted to include the substrate, source and drain regions, second insulation film, floating gate, third insulation film and control gate. An offset transistor is constituted to include the substrate, source and drain regions, third insulation film and control gate. The first insulation film and the impurity region are used as an element isolation region of a memory cell.
