Abstract: According to one embodiment, an apparatus is disclosed. The apparatus includes a memory device having a device identification, The apparatus further includes a low power wake circuit configured to receive a low power wake signal and an identification information, and further configured to initiate a transition of the memory device from a low power state to an active state responsive to an active low power wake signal and the wake identification information matching the device identifier.

Abstract: A multilevel memory subsystem includes a persistent memory device that can access data chunks sequentially or randomly to improve read latency, or can prefetch data blocks to improve read bandwidth. A media controller dynamically switches between a first read mode of accessing data chunks sequentially or randomly and a second read mode of prefetching data blocks. The media controller switches between the first and second read modes based on a number of read commands pending in a command queue.

Abstract: Techniques for proximity based on-die termination (ODT) include a memory device determining what ODT setting to apply during execution of a command by another memory device that is coupled to a same data channel as the memory device based on the memory device's proximity to the other memory device and whether the command is a read command or a write command.

The method further includes detecting the current draw has reached a threshold. The method further includes ceasing or diminishing the write operations in response to the detecting.

Abstract: In an embodiment, a memory controller may determine that one or more neighboring memory cells associated with a target memory cell in a memory device are to be refreshed. The controller may generate a command associated with refreshing the one or more neighboring memory cells. The controller may transfer the command from the memory controller to the memory device containing the target memory cell. The command may direct the memory device to refresh the neighboring memory cells and/or return one or more addresses associated with the neighboring memory cells.

Abstract: Examples are given for techniques for entry to a lower power state for a memory device or die. The examples to include delaying transitions of the memory device or die from a first higher consuming power state to a second relatively lower power state using one or more programmable counters maintained at or with the memory device.
