| 20090016137 | Memory Controller with Programmable Regression Model for Power Control - A memory controller uses a throttling mechanism which estimates a throttling delay for achieving a target power consumption, and periodically blocks all memory commands for a number of clock cycles corresponding to the throttling delay. Idle memory ranks of the memory device are powered down while the memory commands are blocked. A regression model bases the throttling delay on a plurality of operating factors and a plurality of regression coefficients for the operating factors. In the illustrative implementation the operating factors include power consumption, a current number of bank conflicts, a current number of read commands, and a current number of write commands. Different sets of regression coefficients can be programmably stored for use with different system configurations. | 01-15-2009 |
| 20090019243 | DRAM Power Management in a Memory Controller - A memory controller uses a power- and performance-aware scheduler which reorders memory commands based on power priorities. Selected memory ranks of the memory device are then powered down based on rank localities of the reordered commands. The highest power priority may be given to memory commands having the same rank as the last command sent to the memory device. Any memory commands having the same power priority can be further sorted based on one or more performance criteria such as an expected latency of the memory commands and an expected ratio of read and write memory commands. To optimize the power-down function, the power-down command is only sent when the selected memory rank is currently idle, the selected memory rank is not already powered down, none of the reordered memory commands correspond to the selected rank, and a currently pending memory command cannot be issued in the current clock cycle. | 01-15-2009 |
