Through these aspects, utilization of a circuit including a logic mechanism for receiving an enable signal and an address signal, a switching mechanism coupled to the logic mechanism for controlling delivery of the address signal, and a fuse mechanism coupled to the logic mechanism for allowing selective address programming responsive to the address signal in order to produce a desired logic level for a redundant address output signal occurs to form an address programming circuit. Further, selective input of an enable signal to the address programming circuit provides control of the address programming circuit to produce a desired logic level output. Additionally, integration of a plurality of the address programming circuits to form a redundancy programming circuit is achieved with each address programming circuit corresponding to one bit of an input address signal.

    摘要: A method and structure for a refresh operation with a low voltage of logic high in a computer memory structure is provided. The method and system includes first the precharging of a plurality of bit lines and a plurality of complementary bit lines to a voltage higher than the reference voltage. Then at least one of a plurality of word lines and at least one of a plurality of reference word lines are selected. Next, the sense amplifier is activated such that either the plurality of bit lines or the plurality of complementary bit lines discharges to a voltage of logic low. This discharge creates a voltage difference between the plurality of bit lines and the plurality of complementary bit lines. The resulting voltage on the bit lines is restored to the memory cells on the selected word lines. Then, the plurality of bit lines and the plurality of complementary bit lines are restored to the reference voltage. This method and structure allows the use of a logic high voltage lower than 2.0 V without compromising the reliability of the sense amplifier. The implementation of the method and structure of the present invention is cost effective and practical for most if not all DRAM applications.
