    Abstract: Methods, systems, and apparatuses related to memory operation with on-die termination (ODT) are provided. A memory device may be configured to provide ODT at a first portion (e.g., rank) during multiple communications at a second portion (e.g., rank). For example, a memory device may receive a first command instructing a first portion to perform a first communication and instructing a second portion to enter an ODT mode. The device may perform, with the first portion, the first communication with a host while the second portion is in the ODT mode. The device may receive a second command instructing the first portion to perform a second communication, and the device may perform, with the first portion, the second communication while the second portion remains in the ODT mode. The second portion may persist in the ODT mode for an indicated number of communications, or until instructed to exit the ODT mode.

    Abstract: Techniques provided herein compensate for an internal and external timing skew between a data strobe (DQS) and a clock (CLK), by: executing at least one write leveling initialization procedure (WLInit) that uses a mode-register-write (MRW) command to synchronize a timing between a data strobe (DQS) with a clock (CLK) based upon capture of an internal write command. Internal and external timing skew is identified based upon the WLInit. The internal timing skew is skew caused internal to a memory device and the external timing skew is skew caused external to the memory device. A timing between the DQS and the CLK is adjusted based upon the internal and external timing skew.

    Abstract: Apparatuses and methods for a timing domain transfer circuit are disclosed. Disclosed embodiments may be configured to receive an event from one timing domain, output the event to another timing domain, and further configured to mark the event as transferred. An example method includes receiving an Event in based in a first timing domain at a first latch and receiving an intermediate event from the first latch by a second latch. The event is transferred to a second timing domain by the second latch and the first latch is reset based on feedback.
