    摘要： A method, system and computer program product are provided for implementing hardware assisted Dynamic Random Access Memory (DRAM) repair in a computer system that supports ECC. A data register providing DRAM repair is selectively provided in one of the Dynamic Random Access Memory (DRAM), a memory controller, or a memory buffer coupled between the DRAM and the memory controller. The data register is configured to map to any address. Responsive to the configured address being detected, the reads to or the writes from the configured address are routed to the data register.

    摘要： An embodiment is a method for operating a memory system, the method including storing initial calibration values for each of a first frequency and second frequency for a memory device, performing a periodic calibration to determine a calibration update value for operation of the memory device at the first frequency, combining the calibration update value with the initial calibration value for the first frequency to provide an updated calibration for operation of the memory device at an operating frequency of the first frequency and receiving a frequency change request at a memory controller associated with the memory device. The method further includes blocking traffic to the memory device, adjusting operating frequency to the second frequency while the memory device remains powered, combining the calibration update value with the initial calibration value for the second frequency for operation at the second frequency and enabling traffic to the memory device.

    摘要： An embodiment is a method includes writing a first set of memory device parameters to a first mode register in a memory device, wherein the first set of memory device parameters correspond to a first frequency, monitoring selected parameters for the memory system while the memory device operates at the first frequency and predicting a second frequency that the memory device will operate at subsequent to the first frequency, the predicting being based on the monitored selected parameters. The method further includes writing a second set of memory device parameters to second mode register in the memory device, receiving a frequency change request at a memory controller associated with the memory device, the frequency change request to operate at a new frequency and updating the first mode register with the second set of memory device parameters from the second mode register responsive to the new frequency being equal to the second frequency.

    摘要： A method, system and computer program product implement memory performance management and enhanced memory reliability of a computer system accounting for system thermal conditions. When a primary memory temperature reaches an initial temperature threshold, reads are suspended to the primary memory and reads are provided to a mirrored memory in a mirrored memory pair, and writes are provided to both the primary memory and the mirrored memory. If the primary memory temperature reaches a second temperature threshold, write operations to the primary memory are also stopped and the primary memory is turned off with DRAM power saving modes such as self timed refresh (STR), and the reads and writes are limited to the mirrored memory in the mirrored memory pair. When the primary memory temperature decreases to below the initial temperature threshold, coherency is recovered by writing a coherent copy from the mirrored memory to the primary memory.
