Abstract:
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.
