    Abstract: Providing access to an external memory controller to internal error correction bits from a memory device for use as metadata bits by the memory controller. In a first mode the memory device applies internal error correction bits for internal error correction at the memory device. In a second mode the memory device provides access to the internal error correction bits to the memory controller to allow the memory controller to use the data.

    Abstract: A memory subsystem includes a multi-device package including multiple memory devices organized as multiple ranks of memory. A control unit for the memory subsystem sends a memory access command concurrently to some or all of the ranks of memory, and triggers some of all of the memory ranks that receive the memory access command to change on-die termination (ODT) settings. One of the ranks is selected to execute the memory access command, and executes the command while all ranks triggered to change the ODT setting have the changed ODT setting.

    Abstract: A system avoids false sampling due to reflections from previous commands or other noise on a data strobe line. The system uses a normalizer circuit or leaker circuit, and the data strobe line is not optimally terminated or is unterminated. The data strobe line is to receive a burst of data sample pulses or edges and sample a data line based on the edges. The receiving device includes logic that generates a count triggered from an initial edge on the data strobe line, and identifies, based on the count, an initial valid edge of the burst. Any false strobes due to noise or reflections that are received prior to the actual burst can be rejected.

    Abstract: A dynamic priority controller monitors a level of data in a display engine buffer and compares the level of data in the display engine buffer to a plurality of thresholds including a first threshold and a second threshold. When the level of data in the display engine buffer is less than or equal to the first threshold, the dynamic priority controller increases a priority for processing display engine data in a communication channel. When the level of data in the display engine buffer is greater than or equal to the second threshold, the dynamic priority controller decreases the priority for processing the display engine data in the communication channel.

    Abstract: A memory device and a memory controller can interface over a system data bus that has a narrower bandwidth than a data bus internal to the memory device. The memory device and memory controller transfer data over the system data bus on all transfer periods of a burst length, but send fewer bits than would be needed for the exchange to transfer all bits that can be read or written on the internal data bus of the memory device. The memory device can have different operating modes to allow for a common memory device to be used in different system configurations based on the ability to interface with the narrower bandwidth system data bus.
