Assignee: SEAGATE TECHNOLOGY LLC
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method comprising:
storing data to a group of memory cells in a non-volatile memory (NVM);
reading the data from the group of memory cells by applying a first set of read voltages thereto;
accumulating the first set of read voltages into a history distribution;
calibrating the group of memory cells by selecting a second set of read voltages based on the history distribution, adjusting the second set of read voltages to arrive at a third set of read voltages, and using the third set of read voltages to subsequently read the data from the group of memory cells;
incorporating the third set of read voltages into the history distribution to form an updated history distribution that includes at least the first and third sets of read voltages; and
using the updated history distribution to schedule a subsequent data transfer operation upon the group of memory cells.
