A delay locked loop (DLL) circuit for a synchronous semiconductor memory device which can control a delay time of a feedback loop within the DLL circuit according to the magnitude of an external load, and a method of generating information about a load connected to a data pin of a synchronous semiconductor memory device are provided. The DLL circuit includes a replica output driver delaying an internal clock signal by a first delay time to output a first internal clock signal, the first delay time is a delay time of the internal clock signal which is generated by an output driver when a first load of a first magnitude is connected to an output terminal of the output driver, and a transfer/delay circuit transferring the first delay internal clock signal to a phase detector as a second delay internal clock signal when the first load is connected to the output terminal, and outputting the second delay internal clock signal to the phase detector by delaying the first delay internal clock signal by a second delay time, the second delay time is a delay time of the internal clock signal which is generated by the output driver when a second load of a second magnitude, which is larger than the first magnitude, is connected to the output terminal.

A memory system system includes a single in-line memory module (SIMM) which contains a memory device and a signal transmission line connected between the memory device and a connection terminal, and a dual in-line memory module (DIMM) which contains two memory devices and a signal transmission line connected between the two memory devices and a connection terminal. A length of the signal transmission line of the SIMM is longer than a length of the signal transmission line of the DIMM. The load of the memory device of the SIMM is less than the load of memory devices of the DIMM, and the longer length of the signal transmission line of the SIMM increases a signal delay time of the SIMM to compensate for the different loads of the SIMM and DIMM memory devices. The longer length of the signal transmission line of the SIMM may further compensate for a signal transmission line connected between the first and second sockets which receive the SIMM and DIMM, respectively.

A transmission system and method may be provided. The transmission system may transmit 2-bit data for each transmission line set and each transmission line set may include first, second and/or third transmission lines arranged in order. The first, second and/or third transmission lines may respectively transmit first, second and/or third signals each having one of first, second and/or third values such that a combination of a first electric field between the first and second transmission lines and a second electric field between the second and third transmission lines may be made depending on a logic state of the 2-bit data. The transmission system may transmit differential signals using a smaller number of transmission lines and the transmission system may transmit a larger number of signals in the same circuit area.

For ODT (on-die termination) control within a memory module system, just one pin from the memory controller is used for sending command signals indicating an activated one of the memory devices. The activated memory device includes components that are turned on for generating the ODT control signal for controlling an ODT circuit of inactivated memory device(s). The components for generating an ODT control signal within the inactivated memory devices are turned off for minimized power consumption.
