Apparatuses and methods for selective row refreshes are disclosed herein. An example apparatus may include a refresh control circuit. The refresh control circuit may be configured to receive a target address associated with a target plurality of memory cells from an address bus. The refresh control circuit may further be configured to provide a proximate address to the address bus responsive, at least in part, to determining that a number of refresh operations have occurred. In some examples, a plurality of memory cells associated with the proximate address may be a plurality of memory cells adjacent the target plurality of memory cells.

Apparatuses and methods for selective row refreshes

Memory devices and other integrated circuit devices having a first capacitor and a second capacitor with an interposing selective isolation device, and methods of their operation. A selective isolation device is a device selectively in a state of conductance or non-conductance. When the selective isolation device is in a state of conductance, the first capacitor is coupled to the second capacitor. When the selective isolation device is in a state of non-conductance, the first capacitor is electrically isolated from the second capacitor. In memory devices, such parallel coupling of adjacent storage capacitors of adjacent memory cells is useful in increasing beta ratio and providing defect isolation. Such coupling of adjacent storage capacitors generally reduces the number of uniquely addressable memory cells.
