摘要
Devices, systems, and methods include controls for on-die termination (ODT) and data strobe signals. For example, a command to de-assert ODT for a data pin (DQ) during the read operation. An input, such as a mode register, receives an indication of a shift mode register value that corresponds to a number of shifts of a rising edge of the command in a backward or a falling edge in a forward direction. A delay chain delays the appropriate edge of received command the number of shifts in the corresponding direction to generate a shifted edge command signal. Combination circuitry then combines a falling edge command signal with a shifted rising edge command signal to form a transformed command.
