Abstract:
Memory including an array of memory cells might include an input buffer having calibration circuitry, a first input, a second input, and an output; and calibration logic having an input selectively connected to the output of the input buffer and comprising an output connected to the calibration circuitry, wherein the calibration logic is configured to cause the memory to determine whether the input buffer exhibits offset while a particular voltage level is applied to the first and second inputs of the input buffer, and, in response to determining that the selected input buffer exhibits offset, apply an adjustment to the calibration circuitry while the particular voltage level is applied to the first and second inputs until a logic level of the output of the selected input buffer transitions.
