    摘要: A semiconductor memory device includes a plurality of memory cell array blocks, a bit line sense amplifier, a local sense amplifier that can be controlled to be turned on or off, a data sense amplifier, and a controller. The controller activates a local sense control signal for a predetermined duration in response to first and second signals. The first signal is a bit line sense enable signal that activates the bit line sense amplifier, and the local sense amplifier is activated for a predetermined duration after the bit line sense enable signal is activated. The second signal is activated or deactivated in phase with a column selection line signal that connects a pair of bit lines and a pair of local input/output lines. Accordingly, it is possible to turn on or off the local sense amplifier according to operating conditions, thereby increasing a tRCD parameter and reducing the consumption of current. The operating speed of the semiconductor memory device can be improved by combining the local sense amplifier with a current type data sense amplifier that does not require precharging and equalization during a read operation.

    摘要: A high-speed double or quadrature data rate interface semiconductor device and a method thereof are provided. A transmitter (e.g., a data transmitting semiconductor device) for high-speed data transmission transmits a first strobe signal and a second strobe signal, which have a phase difference of 90 degrees there-between, a first group (byte of) data, and a second group (byte of) data. The transmitter adjusts the phase of at least one of the first and second strobe signals based on phase-error information fed back from a receiver and then transmits the phase-adjusted strobe signal to the receiver. The receiver receives the first and second strobe signals from the transmitter and receives the first group (byte of) data and the second group (byte of) data using the first and second strobe signals. The receiver does not require a phase-locked loop (PLL) or a delay-locked loop (DLL), thereby decreasing the circuit area and power consumption of the receiver. In addition, since source synchronization is realized using a strobe signal, phase noise can be efficiently removed.

    摘要: In a method of generating an internal clock for a semiconductor memory device, a doubled clock is generated during operation in a high-speed test mode in response to an external clock. A data clock is generated by delaying the doubled clock so that data read from a memory cell array in the semiconductor memory device is output in synchronization with the external clock. A doubled sync clock synchronized with the external clock is generated by delaying the data clock. An internal clock is generated during operation in the high-speed test mode by delaying the doubled sync clock by a delay amount that corresponds to a delay amount experienced in generation of an internal clock in response to the external clock during operation in a normal mode. Accordingly, the high-speed test operation of the semiconductor memory device can be efficiently performed.

    摘要: A test device for a semiconductor memory device includes a clock frequency multiplier, a data input buffer, a test data generator and a data output buffer. The clock frequency multiplier multiplies an external clock signal having a relatively low frequency provided from an external test device to generate an internal clock signal having a relatively high frequency. The data input buffer buffers test pattern data provided in synchronization to the external clock signal to output the buffered test pattern data. The test data generator generates test data that is to be synchronized to the internal clock signal, using the outputted test pattern data based on a first or a second control signal. The data output buffer outputs the generated test data to a memory core of the semiconductor memory device. The test device generates various test data suitable for a memory test at a high operating speed.
