摘要:
A computer-implemented method, according to one embodiment, includes: receiving a multi-page read request and predicting whether using a multi-plane read operation to read pages of storage space in memory which correspond to the multi-page read request will result in a bit error rate that is in a predetermined range. In response to predicting that using the multi-plane read operation to read the pages will not result in a bit error rate that is in the predetermined range, a threshold voltage shift (TVS) value is computed for the multi-plane read operation. Furthermore, the pages are read using the multi-plane read operation with the computed TVS. Other systems, methods, and computer program products are described in additional embodiments.
