A memory device or other component of a memory module or electronic system may offset a received clock signal. For example, the memory device may receive a clock signal that has a nominal speed or frequency of operation for a system, and the memory device may adjust or offset the clock signal based on other operating factors, such as the speed or frequency of other signals, physical constraints, indications received from a host device, or the like. A clock offset value may be based on propagation of, for example, command/address signaling. In some examples, a memory module may include a registering clock driver (RCD), hub, or local controller that may manage or coordinate clock offsets among or between various memory devices on the module. Clock offset values may be programmed to a mode register or registers.

APPARATUSES AND METHOD FOR REDUCING ROW ADDRESS TO COLUMN ADDRESS DELAY
Publication/Patent Number: US2021027821A1 Publication Date: 2021-01-28 Application Number: 17/035,462 Filing Date: 2020-09-28 Inventor: Kawamura, Christopher   Assignee: Micron Technology, Inc.   IPC: G11C8/18 Abstract: Apparatuses and methods for reducing row address (RAS) to column address (CAS) delay (tRCD) are disclosed. In some examples, tRCD may be reduced by providing a non-zero offset voltage to a target wordline at an earlier time, such as during a threshold voltage compensation phase of a sense operation. Setting the wordline to a non-zero offset voltage at an earlier time may reduce a time for the wordline to reach an activation voltage, which may reduce tRCD. In other examples, protection against row hammer attacks during precharge phases may be improved by setting the wordline to the non-zero offset voltage.
