Abstract
Systems, apparatuses, and methods provide for technology that stores a sampled dynamic start voltage value based on a fast to program plane. A current multi-plane program operation is received corresponding to a current cell block and wordline pair associated with a current enabled plane of a plurality of enabled planes. A block list is scanned based on the current cell block and wordline pair. The block list includes a plurality of entries including a reference start voltage corresponding to a reference cell block and wordline pair associated with a reference enabled plane. Additionally, the reference start voltage is reused as a dynamic start voltage in response to finding a match between the current cell block and wordline pair as compared to the reference cell block and wordline pair. Such a match is performed only for a least enabled plane of the plurality of enabled planes.
