Abstract

Throttling of memory access commands. Accesses to rows of a memory device are monitored for a timeframe. The timeframe is divided into at least two sub-frames. If the number of accesses for any of the rows during a first sub-frame exceeds a first threshold throttling accesses to the accessed row at a first rate. Not throttling accesses to the accessed row if the number of accesses to the accessed row does not exceed the first threshold. The first threshold is associated with risk of data corruption on a row physically adjacent to the accessed row. If a number of accesses for the accessed row during a second sub-frame exceeds a second threshold, throttling accesses to the accessed row at a second rate. Not throttling accesses to the accessed row if the number of accesses to the accessed row does not exceed the second threshold. The second threshold is greater than the first threshold. The second throttling rate is greater than the first throttling rate.
