Abstract:
Several embodiments of memory devices and systems with offset memory component automatic calibration error recovery are disclosed herein. In one embodiment, a system includes at least one memory region and calibration circuitry. The memory region has memory cells that read out data states in response to application of a current read level signal. The calibration circuitry is operably coupled to the at least one memory region and is configured to determine a read level offset value corresponding to one or more of a plurality of offset read level test signals, including a base offset read level test signal. The base offset read level test signal is offset from the current read level signal by a predetermined value. The calibration circuitry is further configured to output the determined read level offset value.
