    Abstract: A semiconductor device includes an ODT (on die termination) pin coupled to a tester that applies a tester termination control signal thereon. The semiconductor device also includes a measure path that transmits the tester termination control signal from the ODT pin to an ODT circuit during measurement of a parameter of the semiconductor device. The ODT pin and the measure path advantageously allow for control of the ODT circuit by the tester for more accurate parameter characterization.

    Abstract: The invention provides an improved memory system that addresses signal degradation due to transmission line effects. The improved memory system includes a first buffer, at least one first memory device coupled to the first buffer, and a plurality of signal traces. The first buffer and memory device are mounted on a motherboard. Likewise, the plurality of signal traces is routed on the motherboard. Doing so eliminates stub loads that cause signal reflection that, in turn, result in signal degradation.

    Abstract: Provided are a reset circuit of a data path using a clock enable signal, a reset method and a semiconductor memory device having the reset circuit. The reset circuit includes an external voltage detector and a second reset signal generator, in which the second reset signal is used to reset a block related to a data path of the semiconductor memory device. The external voltage detector detects the level of an external voltage and generates a first reset signal. The second reset signal generator performs a logical sum of an external signal, which is externally input, and the first reset signal, and generates a second reset signal. The first reset signal is used to reset blocks other than the blocks related to the data path. The external signal is a clock enable signal. In the soft reset, the blocks related to the data path are reset using the external signal which is applied at a certain level. Thus, data conflicts or ineffective data can be prevented in executing operations according to the read/write commands which are applied after the soft reset.

    Abstract: A semiconductor memory device capable of improving common bus efficiency is disclosed. The device comprises an address shifting circuit for delaying an address by an n+m number of clock cycles in response to a clock signal, a control signal generating circuit for combining a column address strobe (CAS) latency of n-value and one of first and second operation signals to generate a control signal, and a switching circuit for outputting the address delayed by the n+m number of clock cycles output from the address shifting circuit in response to the control signal. The first operation signal indicates that the n-value of the CAS latency is less than a predetermined value and write latency is fixed. The second operation signal indicates that the n-value of the CAS latency is equal to or greater than the predetermined value and the write latency is variable.
