    摘要: A device connected between first and second voltage feed lines includes an information storing circuit having a fuse for storing information by blowing or not blowing the fuse, a voltage level conversion circuit connected to at least one of the first and second voltage feed lines and outputting a voltage lower than a voltage between the first and second voltage feed lines to the information storing circuit, and a circuit connected between the first and second voltage feed lines, for outputting a detection signal in response to a voltage value at the fuse in the information storing circuit to which the voltage is applied from the voltage level conversion circuit and which voltage value is varied with the blown or unblown state of the fuse.In a normal operation, the voltage output from the voltage level conversion circuit can be set as low as possible to restrain electromigration caused at the vicinity of the blown portion of the fuse to which the voltage is applied, but higher than the threshold voltage of the information detection circuit.

    摘要: A semiconductor integrated circuit which includes therein at least one inspection circuit for inspecting a voltage level produced at an internal node to be inspected. The inspection circuit has at least a control signal input portion connected to the internal node to be inspected and an input part connected to an external input/output pin. The inspection circuit includes a series-connected transistor and diode connected between a power source and the input portion, a capacitor connected between a gate of the transistor and the input portion, and a transfer gate transistor connected between the control signal input portion and the gate of the transistor. The inspection circuit discriminates the level at the internal node according to a flow or nonflow of a current, via the external input/output pin, when a particular signal having a voltage level higher than the power source level is supplied to the external input/output pin.

    摘要: An MIS transistor circuit which is operated alternately in a reset state and in an active state, comprises a voltage holding circuit for holding a power supply voltage applied in each reset state so as to provide a clamped voltage. The clamped voltage is applied during each active state to the desired nodes of the MIS transistor circuit as an actual power supply voltage, whereby error operation due to voltage fluctuation of the power supply voltage is prevented.

    摘要: A semiconductor memory device includes: a memory cell array constituted of a plurality of memory cell array units; transfer gates inserted in bit lines between the adjacent memory cell array units; a first and a second column decoders connected to both ends of bit lines in which the transfer gates are inserted; a row decoder connected to word lines of the memory cell array. The row decoder is adapted to be divided selectively in two parts; and two sets of row/column addresses are supplied to the column decoders and the row decoder. Therefore, simultaneous separate accesses to the memory cell array are carried out by the two sets of row/column addresses.

    摘要: A non-volatile storage device (1) has non-volatile memory units (FARY0 to FARY3), buffer units (BMRY0 to BMRY3) and a control unit (CNT), and the control unit can control a first access processing between an outside and the buffer unit and a second access processing between the non-volatile memory unit and the buffer unit upon receipt of directives from the outside separately from each other. The control unit can independently carry out an access control over the non-volatile memory unit and the buffer unit in accordance with the directives sent from the outside, respectively. Therefore, it is possible to set up next write data to the buffer unit simultaneously with the erase operation of the non-volatile memory unit or to output once read storage information to the buffer unit at a high speed as in a cache memory operation in accordance with the directive sent from the outside. Consequently, it is possible to reduce the overhead of a data transfer for reading/writing data from/to the non-volatile storage device.
