    摘要: A novel semiconductor memory device includes an address detection circuit that produces a short-width pulse in response to the detection of an address change. A column decoder-activating signal generator detects the start of the short-width pulse and in response generates a column decoder-activating signal. A second detection circuit detects the conclusion of the short-width pulse and generates a second pulse that triggers a preamplifier-activating signal that activates a preamplifier and latches the data that is present on the input/output line. A reset signal generator produces a reset signal to deactivate the column decoder-activating signal and to delay the preamplifier-activating signal. The preamplifier-activating signal generator and the reset signal generator are reset while the first pulse is output.

    摘要: A word line driving signal generating circuit and a sense amplifier activating signal generating circuit are provided for every partitioned memory cell array. When the levels of an external RAS signal and an external CAS signal have a predetermined relation and an external RNC signal remains at a predetermined potential or more, a refresh operation is started. A refresh address is generated from a refresh address counter in a sense restore control circuit. All of the memory cell arrays are simultaneously refreshed in response to the address. On this occasion, an operation for selecting a column by a column decoder provided in each of the memory cell arrays is inhibited. In the case in which an input of the external RNC signal is not prepared, when the levels of the external RAS signal and the external CAS signal have a predetermined relation and this state is held in a predetermined time period or more, the same refresh operation as described above is started.

    摘要: In a slew rate adjusting circuit for producing a timing signal determining an output slew rate, a delay circuit for producing an output timing signal is formed of delay circuits with a variable number of delay stages, and the delay time of the output timing signal is adjusted in a step of a delay time of the delay stage in accordance with slew rate adjusting data. A large adjustment margin can be ensured for the output slew rate determining the changing rate of the output data.

    摘要: A transfer gate is provided between an input terminal, receiving voltage Vh of the super Vcc level when a special operating mode is set, and an inverter and an n channel MOS transistor included in a super Vcc detection circuit of a DRAM. The transfer gate is rendered conductive only during a potential detection period during which signal WCBR attain an "H" level. Therefore, a leakage current flowing from the input terminal through the n channel MOS transistor to a ground terminal can be minimized, thereby reducing a consumed current.

    摘要: There are provided upper and lower data I/O terminal groups, each forming a unit for input/output of data. When an early write detecting circuit included in a clock generating circuit detects designation of an early write mode and one of the groups is designated for writing, lower or upper input buffers controlled by write control circuit takes in the data. Concurrently, in response to the detection of mode, lower or upper output buffer uses, for reading, the other group not taking in data for writing. In this mode, therefore, the write and read operations are executed simultaneously. Thereby, simultaneous operation of the write and read data is allowed, and a data processing speed is improved.
