    摘要: In a defect relieving technology which replaces defective memory cells of a semiconductor memory device by spare memory cells, use is made of an associative memory. Address information of a defective memory cell is stored as a reference data of the associative memory, and new address information of a spare memory cell is written down as output data of the associative memory. A variety of improvements are made to the associative memory. For instance, a plurality of coincidence detection signal lines of the associative memory are divided into at least two groups, and one group among them is selected by switching means. Reference data of the associative memory comprises three values consisting of binary information of "0" and "1", and don't care value "X". The associative memory further includes a plurality of electrically programable non-volatile semiconductor memory elements.

    摘要: A semiconductor memory having an error correcting function is provided, which has a device by which the user finds no difficulty in making use of the semiconductor memory and can test it with ease. In the semiconductor memory, a signal indicative of the completion of the preparation for reading/writing is outputted from the memory so that the user, after detecting the output of this signal, performs reading/writing data. To facilitate tests, such as a memory cell test for a redundant bit (check bit), an encoding circuit test and a decoding circuit test, the present invention provides that the arranged tests can be made independently of each other.

    摘要: A highly reliable and high speed ferroelectric memory having a high degree of integration. In a ferroelectric memory having a multiple of memory cells M1, each constituted by one transistor and one ferroelectric capacitor, in the normal operation, the ferroelectric memory is used as a volatile memory in which a voltage on a storage node ST1 stores information in a DRAM mode. Both the electric potential at the plate PL1 of the ferroelectric capacitor and a precharge electric potential on a data line DL1(j) are Vcc/2. When the a power supply voltage is turned on, a polarization state is detected as a ferroelectric memory of a plate electric potential of Vcc/2 and a precharge electric potential of Vss (or Vcc) and the read operation is performed a FERAM mode. The switching between the DRAM mode and the FERAM mode is executed by generating a signal to designate the FERAM mode in the memory along with the turn-on of the power supply and by generating a signal to designate the DRAM mode after completion of the conversion operation from nonvolatile information to volatile information.

    摘要: In a voltage converter provided in a semiconductor device and supplying an internal supply voltage to a circuit in the semiconductor device, a circuit is provided for generating a first voltage whose dependency on an external supply voltage is regulated to a predetermined small value, while another circuit is provided for generating a second voltage whose dependency on the external supplying voltage is larger than the dependency of the first voltage. Another circuit selects the first voltage when the semiconductor device is in a state of a standard operation and selects the second voltage when the device is in another state of operation, such as testing or aging. The selected voltage may be converted by a differential amplifier which is constituted by a load of P-channel MOS transistors and a source-coupled pair of N-channel MOS transistors. An output of the differential amplifier is fed back through a directly coupled voltage lowering circuit which generates the converted output.
