Abstract: A method of operating memory devices disposed in different ranks of a multi-rank memory device and sharing a signal line includes receiving, in all of the memory devices included in the multi-rank memory device, on-die termination (ODT) state information of the signal line. The method further includes storing, in each of the memory devices of the multi-rank memory device, the ODT state information of the signal line in a mode register. The method further includes generating, in each of the memory devices of the multi-rank memory device, a control signal based on the ODT state information of the signal line stored in the mode register. The method further includes changing, in each of the memory devices of the multi-rank memory device, an ODT setting of the signal line in response to the control signal.

Abstract: Disclosed is an operating method of a memory device communicating with a memory controller, which includes receiving a first command from the memory controller, the first command indicating initiation of synchronization of a data clock signal and defining a clock section corresponding to the synchronization, preparing a toggling of the data clock signal during a preparation time period, processing a first data stream based on the data clock signal toggling at a reference frequency, and processing a second data stream based on the data clock toggling at the reference frequency and extended for a period of the defined first clock section.

Abstract: A memory device having a plurality of voltage regions and a method of operating the same are provided. The memory device includes a memory cell array, a data path region including data processing blocks transmitting read/write data from/to the memory cell array during read/write operations, and a control signal path region including control blocks controlling the data processing blocks during the read/write operations. The data path region selectively receives a first high power voltage or a first low power voltage in accordance with an operating mode of the memory device. The control signal path region receives the first high power voltage regardless of the operating mode.

Abstract: Disclosed is a memory device which includes a memory cell array that stores first data and first parity data, an error correction code (ECC) circuit that performs ECC decoding based on the first data and the first parity data and outputs error-corrected data and a decoding status flag, and an input/output circuit that provides the error-corrected data and the decoding status flag to a memory controller. The ECC circuit includes a syndrome generator that generates a syndrome based on the first data and the first parity data, a syndrome decoding circuit that decodes the syndrome to generate an error vector, a correction logic circuit that generates the error-corrected data based on the error vector and the first data, and a fast decoding status flag (DSF) generator that generates the decoding status flag based on the syndrome, without the error vector.
