A memory includes a local control circuitry that manages scrub transactions using a set of sense amplifiers separate from those used for access (read and write) transactions. The local control circuitry interrupts scrub transactions to prioritize access requests, thereby offering improved memory performance. The local control circuitry also divides scrub transactions into phases and periods based on whether the scrub transaction requires access to bitlines used for read and write access. This division allows the local control circuitry to interleave and interrupt scrub transactions with access transactions in a manner that minimizes access interference.
