摘要： A method of controlling On-Die Termination (ODT) resistors of memory devices sharing signal lines is provided. The ODT controlling method comprises setting an ODT control enable signal of each of the memory devices and address/command or data termination information to a mode register of the corresponding memory device, and controlling resistances of ODT resistors of the signal lines in the memory devices in response to the address/command or data termination information and termination addresses. When only one of the memory devices is activated, ODT resistors of the activated memory device are set to a first resistance. When all the memory devices are activated, ODT resistors of the memory devices are set to a second resistance.

摘要： A method may be provided to communicate a plurality of groups of output data bits representing a respective plurality of groups of input data bits over a data bus with each group of output data bits and each group of input data bits have an equal data width. Each of the plurality of groups of input data bits at may be received at a data register. For each group of input data bits received at the data register, if a number of data bits of the group of input data bits having a first logic level is greater than half of the data width, the group of input data bits are inverted, the inverted group of input data bits are transmitted as a respective group of output data bits in parallel over the data bus, and an inversion flag associated with the respective group of output data bits is transmitted. For each group of input data bits received at the data register, if a number of data bits of the group of input data bits having a second logic level different than the first logic level is greater than half of the data width, the group of input data bits is transmitted without inversion as a respective group of output data bits in parallel over the data bus, and a non-inversion flag associated with the respective group of output data bits is transmitted. Related systems are also discussed.
