Abstract
A computer-implemented method, according to one approach, is for calibrating read voltages associated with a block of memory having more than one word-line therein. The computer-implemented method includes: for each of the word-lines in the block: calculating an absolute shift value for a reference read voltage associated with the given word-line. A relative shift value is also determined for each of the remaining read voltages associated with the given word-line, and the relative shift values are determined with respect to the reference read voltage. Moreover, each of the read voltages associated with the given word-line are adjusted using the absolute shift value and each of the respective relative shift values.
