Abstract
A computer-implemented method, according to one embodiment, includes: determining a current operating state of a block of memory. The block includes more than one type of page therein, and at least one read voltage is associated with each of the page types. The current operating state of the block is further used to produce a hybrid calibration scheme for the block which identifies a first subset of the read voltages, and a second subset of the read voltages. The read voltages in the second subset are further organized in one or more groupings. A unique read voltage offset value is calculated for each of the read voltages in the first subset, and a common read voltage offset value is also calculated for each grouping of read voltages in the second subset.
