    摘要: In a multi-bit test, an I/O combiner degenerates data of a plurality of bits read from a memory cell array to first to fourth data bus pairs in parallel and outputs the degenerated data to a fifth data bus. A read amplifier compares a logic level of the degenerated data received from the I/O combiner with a logic level of expected value data. If the logic level of the degenerated data coincides with the logic level of the expected value data, the read amplifier determines that data write and read to and from the plurality of bits have been normally performed. As a result, a semiconductor memory device can detect a word line defect in the multi-bit test.

    摘要: By devising the arrangement of memory arrays surrounding the central region of the chip, the total length of a data bus can be reduced. The memory arrays are arranged such that one of two memory arrays that are located at the positions point-symmetric with respect to the central region corresponds to lower DQ terminals, and the other memory array corresponds to upper DQ terminals. Preferably, the memory arrays corresponding to the upper DQ terminals and the memory arrays corresponding to the lower DQ terminals are each located collectively. Thus, a semiconductor memory device with improved data propagation characteristics on the data bus can be provided.

    摘要: A control circuit & mode register outputs a signal responsive to each command to a VDC control circuit. The VDC control circuit outputs a signal PWRUP changing the quantity of a through current Ic of a comparator stored in a VDC in response to the command. The VDC control circuit internally generates a signal of which pulse width corresponds to a prescribed delay time, in response to input of the command. Therefore, activation of each bank may not be monitored but current consumption can be reduced by preferably controlling a power supply current while minimizing the number of delay circuits and wires.

    摘要: A semiconductor memory device includes a mode detection circuit for generating a mode detection signal in response to external input signals /RAS, /CAS and /WE, an internal potential generating circuit for generating and supplying to an output node an internal potential, in response to an activated potential control signal, and an internal potential control circuit for activating a potential control signal when a potential at the output node has not yet reached a predetermined potential in a case where mode detection signal indicates a mode other than the test mode, and for activating the potential control signal when the potential at the output node has not yet reached an externally supplied external reference potential in a case where the mode detection signal indicates the test mode. When external input signals are applied at a predetermined timing, a mode detection signal indicating the test mode is generated, and when the potential at the output node of the internal potential generating circuit has not yet reached the external reference potential, an internal potential is generated and supplied to the output node. Therefore, the internal potential can be controlled in accordance with the external reference potential.

    摘要: A DLL clock control circuit determines whether or not an operating frequency is a low frequency satisfying a prescribed condition, based on signals received from a DLL circuit and a READ control circuit. When the DLL clock control circuit determines that the operating frequency is a low frequency, the DLL clock control circuit outputs a DLL clock received from the DLL circuit if a first signal to be activated in response to a READ command is activated, while when determining that an operating frequency is not a low frequency, outputting a DLL clock received from the DLL circuit if a second signal to be activated in response to an ACT command is activated. As a result, a semiconductor memory device can guarantees a data output operating in data reading and can reduce power consumption during active standby.
