Abstract
Memory devices, memory systems, and methods of operating memory devices and systems are disclosed in which a single command can trigger a memory device to perform multiple operations, such as a single refresh command that triggers the memory device to both perform a refresh command and to perform a mode register read. One such memory device comprises a memory, a mode register, and circuitry configured, in response to receiving a command to perform a refresh operation at the memory, to perform the refresh operation at the memory, and to perform a read of the mode register. The memory can be a first memory portion, the memory device can comprise a second memory portion, and the circuitry can be further configured, in response to the command, to provide on-die termination at the second memory portion of the memory system during at least a portion of the read of the mode register.
