Abstract: A memory controller maintains a mapping of target ranges in system memory space interleaved two-ways across locations in a three-rank environment. For each range of the target ranges, the mapping comprises a two-way interleaving of the range across two ranks of the three-rank environment and offsets from base locations in the two ranks. At least one of the ranges has offsets that differ relative to each other. Such offsets allow the three ranks to be fully interleaved, two ways. An instruction to read data at a rank-agnostic location in the diverse-offset range causes the memory controller to map the rank-agnostic location to two interleaved locations offset different amounts from their respective base locations in their ranks. The controller may then affect the transfer of the data at the two interleaved locations.

Abstract: A computing apparatus in an implementation comprises a memory device and a controller. The memory device comprises banks of cells arranged in rows and columns and is configured to maintain a row-level activation count on a per-row basis. The controller is operatively coupled with the memory device and is configured to maintain a bank-level activation count on a per-bank basis. The controller initiates a refresh operation for at least a given row in the memory device when at least both the bank-level activation count for a given bank satisfies a bank-level condition, and the row-level activation count for the given row satisfies a row-level condition.
