摘要
Apparatuses and methods for pure-time, self-adopt sampling for RHR refresh. An example apparatus includes a memory bank comprising a plurality of rows each associated with a respective row address, and a sampling timing generator circuit configured to provide a timing signal having a plurality of pulses. Each of the plurality of pulses is configured to initiate sampling of a respective row address associated with a row of the plurality of rows to detect a row hammer attack. The sampling timing generator includes first circuitry configured to provide a first subset of pulses of the plurality of pulses during a first time period and includes second circuitry configured to initiate provision of a second subset of pulses of the plurality of pulses during a second time period after the first time period.
