Hardware and software hybrid configuration of dram channel interleaving management

Abstract

Various embodiments include a memory controller and methods for implementing functions of the memory controller for hardware and software hybrid configuration of memory channel interleaving management. Embodiments may include a memory controller having a signaling mechanism configured to provide a configuration signal for indicating to the memory controller a layer of a memory channel interleaving hierarchy for software memory channel interleaving management, a processor configured to read the configuration signal and select the layer of the memory channel interleaving hierarchy for software memory channel interleaving management based on the configuration signal, and an integrated circuit configured to implement memory channel interleaving according to a layer of the memory channel interleaving hierarchy for hardware memory channel interleaving management. In some embodiments, the layers for software or hardware memory channel interleaving management may include any of an intra-memory channel group, an inter-memory channel group, or an inter-die memory channel group layer.
