Abstract: Examples include techniques associated with allocating memory capacity of a memory partitioned to include a first region arranged to include in-line or in-band error correction control (IBECC) memory and a second region arranged to include non-IBECC memory. The first and second regions can be re-sized based on usage of either region reaching a threshold.

Abstract: Logical memory is divided into two regions. Data in the first region is always retained. The first region of memory is designated online (or powered on) and is not offlined during standby or low power mode. The second region is the rest of the memory which can be potentially placed in non-self-refresh mode during standby by offlining the memory region. Content in the second region can be moved to the first region or can be flushed to another memory managed by the operating system. When the first region does not have enough space to accommodate data from the second region, the operating system can increase the logical size of the first region. Retaining the content of the first region by putting that region in self-refresh and saving power in the second region by not putting it in self-refresh is performed by an improved Partial Array Self Refresh scheme.

Abstract: Techniques and mechanisms for a power management circuit to monitor a power domain during one or more attempts to configure a low power state of the power domain. In an embodiment, the one or more attempts are performed during an instance of a local power state at a processor that is coupled to the power management circuit. The monitoring is to detect for a condition wherein the power domain has been in a power state, other than the low power state, for longer than a predetermined threshold length of time. Where the condition is detected, the power management circuit generates one or more signals which change the local power state of the processor, or interrupt an operating system that is executed with the processor. In another embodiment, the power management circuit provides analytic data based on the monitoring of the one or more attempts.
