Abstract
Control logic in a memory device receives a request to perform a read operation to read data from a memory array of a memory device, the request comprising an indication of a segment of the memory array where the data is stored, and performs a first coarse valley tracking calibration operation on the segment of the memory array. The control logic further configures a read voltage level and one or more parameters associated with the read operation based on a result of the first coarse valley tracking calibration operation and performs a second fine valley tracking calibration operation on the segment of the memory array using the configured read voltage level and the configured one or more parameters.
