Abstract
Systems and methods are provided for trimming RTTs in a memory device. The effective termination resistance (RTT) of the ODT may be adjusted by adjusting one or more driver units having predefined values (e.g., 240Ω). Because PVT characteristics may impact the driver unit values, resistances of the driver units may be fluctuated away from the predefined values (e.g., 240Ω). ZQ calibration signals may be used to calibrate the resistances of the driver units to the predefined values (e.g., 240Ω) to trim the RTTs. Separate ZQ calibration signals may be generated for different circuits (e.g., a circuit associated with DQ pad, a circuit associated with CA pad). In addition, two ZQ calibration signals may be generated simultaneously by a ZQ circuit during the same time period.
