摘要:
In a particular embodiment, a dynamic interleaving system changes the number of interleaving channels of a multi-channel memory based on a detected level of bandwidth requests from a plurality of master ports to a plurality of slave ports. At a low level of bandwidth requests, the number of interleaving channels is reduced.

A memory power management system and method supporting multiple power modes for powering memory channels. The power management system can include a memory controller that controls the memory channel; a throughput detector that detects a requested throughput of the memory channel; a power control logic that determines a desired power mode corresponding to the requested throughput; and a power control device that supplies a desired voltage of the desired power mode to the memory channel. The power management system can include multiple memory controllers for controlling a multi-channel memory independently. The method includes detecting a requested throughput for the memory channel; determining a desired voltage related to the requested throughput; requesting the desired voltage from a voltage device; and applying the desired voltage to the memory channel. In some embodiments, the method only applies the desired voltage if it does not change for a threshold time duration.
摘要:
A load balancing in a multiple DRAM system comprises interleaving memory data across two or more memory channels. Access to the memory channels is controlled by memory controllers. Bus masters are coupled to the memory controllers via an interconnect system and memory requests are transmitted from the bus masters to the memory controller. If congestion is detected in a memory channel, congestion signals are generated and transmitted to the bus masters. Memory requests are accordingly withdrawn or rerouted to less congested memory channels based on the congestion signals.

A non-uniform interleaving scheme in a multiple channel DRAM system comprises associating memory data with a memory address, associating address zones to predetermined ranges of memory addresses and associating predetermined interleaving granularities with the address zones. Memory data is interleaved across two or more memory channels such that a predetermined interleaving granularity is applied to each address zone.
