    Abstract: PROBLEM TO BE SOLVED: To provide a new microcell redundancy system for a wide band width embedded DRAM having a SRAM cache interface.
    SOLUTION: For each bank of microcell array units comprising the eDRAM, at least one microcell unit is prepared as the redundancy to replace a defected microcell within the bank. After array testing, any defective microcell inside the bank is replaced with a redundancy microcell for that bank. A fuse bank structure implementing a lookup table is established for recording each redundant microcell address and its corresponding repaired microcell address. In order to allow simultaneous multi-bank operation, the redundant microcells may only replace the defective microcells within the same bank.

    Abstract: PROBLEM TO BE SOLVED: To provide a method, as well as structure, for manufacturing a dynamic random access memory device and a related transistor at the same time.
    SOLUTION: A channel region and a capacitor opening are formed in a substrate by this method. Then a capacitor conductor is allowed to stick to the capacitor opening. A single insulator layer is formed above the channel region and the capacitor conductor at the same time. The single insulator layer contains a capacitor node dielectrics above the capacitor conductor while a gate dielectrics above the channel region. A single conductor layer is patterned above the single insulator layer at the same time. The single conductor layer contains a gate conductor above the gate dielectrics while a ground plate above the capacitor node dielectrics.

    Abstract: PROBLEM TO BE SOLVED: To refresh data in a DRAM cache memory in a computer system without generating disadvantage (e.g. delay in a processor). SOLUTION: When a desired address outputted from the processor is detected, a normal refreshing operation is stopped, the desired address is compared with a TAG address stored in a TAG memory 192 and selected by the processor, a refresh address to be generated on the basis of the oldness of data is generated in order to refresh data stored in the cache memory, reading/writing operation for a word line accessed by the desired address is executed, and data on the word line accessed by the refresh address are refreshed to execute the data refreshing operation of the DRAM cache memory. In this case, the reading/ writing operation and the data refreshing operation are simultaneously executed.

    Abstract: PROBLEM TO BE SOLVED: To provide an improved clock generator whose clock skew is reduced. SOLUTION: A clock generator includes a waveform generator and a de-skew circuit. A waveform generator is clock-operated according to an input clock signal, and generates a waveform signal. The de-skew circuit is connected to the waveform generator, and generates an output clock signal by gate- controlling the waveform signal from the waveform generator with the input clock signal so that the skew of an output clock signal can be made smaller than the input clock signal.

    Abstract: PROBLEM TO BE SOLVED: To provide a more simplified substitutional method of the conventional damascene approach. SOLUTION: The cloisonne approach includes a step of coating a semiconductor substrate with a photosensitive polymer, such as pyrrole having a silver salt, aniline, etc. A conductive polymer is exposed to a wet developing solution, by using standard photolithography and the resists developing method and only conductive polymer wires are left on a substrate by removing part of the exposed conductive polymer region. Then an insulating dielectric layer is adhered to the whole structure, and conductive polymer wires are produced by planarizing an insulator by the chemical mechanical polishing (CMP). Another embodiment of this invention includes a method and structure for a self- planarizing interconnecting material containing the conductive polymer. Consequently, the number of treating steps can be reduced, as compared with the conventional technology.

    Abstract: PROBLEM TO BE SOLVED: To provide a voltage control system and a method for keeping a voltage level generated inside a semiconductor chip. SOLUTION: The method comprises a step, in which the internal voltage supply level is sampled intermittently in a low electric power mode or a 'sleep' mode, a step in which the internal voltage supply level is compared with a prescribed voltage reference level, and a step in which a voltage supply generator is activated, when an internal voltage supply level is dropped to a level being less than the prescribed voltage reference level and the internal voltage supply level is raised. When the voltage supply level is restored to the prescribed voltage reference level, the voltage supply generator is made inactive. A sampling cycle can be adjusted appropriately according to chip conditions, chip temperature, and chip size. In one embodiment, the voltage control system and the method are performed by a DRAM circuit at refresh-operation. A voltage level, including band gap reference voltage of a DRAM, line voltage for boosted word lines, LOW voltage for word lines, HIGH voltage for bit lines, and bit line equalizing voltage is suitable for sampling.
