    Abstract: A method of refreshing a memory device includes performing normal refresh operations on memory cell rows in response to a refresh command and performing self-refresh operations on the memory cell rows according to a refresh clock signal in response during a self-refresh mode of the memory device between a self-refresh enter command and a self-refresh exit command. The refresh clock signal has a first self-refresh cycle before the self-refresh begins and a second self-refresh cycle, which may be longer than the first self-refresh cycle, after the self-refresh begins. In some examples, no self-refresh may be performed by the memory device during a self-refresh mode.

    Abstract translation: 刷新存储器件的方法包括响应于刷新命令对存储器单元行执行正常刷新操作，并且在存储器的自刷新模式期间响应于刷新时钟信号对存储器单元行执行自刷新操作 设备在自刷新输入命令和自刷新退出命令之间。 刷新时钟信号在自刷新开始之前具有第一自刷新周期，并且在自刷新开始之后具有可能比第一自刷新周期长的第二自刷新周期。 在一些示例中，在自刷新模式期间，存储器件不能执行自刷新。

    Abstract: A memory module includes a first memory group including a plurality of first semiconductor memory devices, and a second memory group including a plurality of second semiconductor memory devices. The first semiconductor memory devices and the second semiconductor memory devices share a command/address bus. The first semiconductor memory devices perform a first operation in response to a command signal received by the first semiconductor memory devices from the command/address bus and the second semiconductor memory devices perform a second operation, different from the first operation, in response to the same command signal received by the second semiconductor memory devices from the command/address bus.

    Abstract: A memory device performing an internal copy operation is provided. The memory device may receive a source address, a destination address, and page size information together with an internal copy command, compares the source address with the destination address, and performs an internal copy operation. The internal copy operation may be an internal block copy operation, an inter-bank copy operation, or an internal bank copy operation. The internal copy operation may be performed with respect to one-page data, half-page data, or quarter-page data, based on the page size information. The memory device may output as a flag signal a copy-done signal indicating that the internal copy operation has been completed.
