    Abstract: A memory device having on-die error checking and correction (ECC) circuitry can provide uncorrected data in response to a read command. The ECC circuitry can perform error correction for errors detected, generating the corrected data in parallel with providing the uncorrected data. The memory device stores the corrected data internally to the memory device. When an error is detected, the memory device provides an indication to the memory controller, which can then request the corrected data.

    Abstract: Protocol layer logic in a protocol stack receives an indication that a particular mode is to be utilized on a die-to-die (D2D) link connecting a first device to a second device. The protocol layer logic generates data to be sent on the D2D link to adapt the particular data format to a flit format defined for use on the D2D link in the particular mode, the flit format comprises providing a set of reserved fields to be completed by an adapter block positioned between the protocol circuitry and a physical layer block. The data in the flit format is sent to the data to the adapter block to prepare the data for transmission over the D2D link.

    Abstract: Systems, methods, and apparatuses associated with an approximate majority based data bus inversion technique are disclosed. A method comprises obtaining, at a first device connected by a plurality of lanes to a second device, original data comprising first bits and second bits, where the first bits are to be transmitted in a new clock cycle via first lanes of the plurality of lanes, and the second bits are to be transmitted in the new clock cycle via second lanes of the plurality of lanes. The method further includes determining whether a first criterion associated with the first bits is met, determining whether a second criterion associated with the second bits is met, and transmitting an inverted version of the original data via the plurality of lanes based, at least in part, on determining that the first criterion and the second criterion are met.

    Abstract: An adapter is provided that includes a first interface to couple to a particular device, where link layer data is to be communicated over the first interface, and a second interface to couple to a physical layer (PHY) device. The PHY device includes wires to implement a physical layer of a link, and the link couples the adapter to another adapter via the PHY device. The second interface includes a data channel to communicate the link layer data over the physical layer, and a sideband channel to communicate sideband messages between the adapter and the other adapter over the physical layer. The adapter is to implement a logical PHY for the link.

    IPC: G06F13/42

    Abstract: A port is to couple to another die over a die-to-die (D2D) link and includes physical layer (PHY) circuitry including a first number of sideband lanes to carry data for use in training and management of the D2D link, and a second number of mainband lanes to implement a main data path of the D2D link. The mainband lanes include a forwarded clock lane, a valid lane, and a plurality of data lanes. A logical PHY coordinates functions of the sideband lanes and the mainband lanes.
