In some embodiments, the memory has non-volatile memory cells arranged into addressable blocks. Each memory cell is configured to store multiple bits. A program/read control circuit programs data sets to and reads data sets from the memory cells in the addressable blocks to service a sequence of host access commands. The circuit concurrently performs background reads in conjunction with the servicing of the host access commands. The background reads result in the reading of a different data set from each of the addressable blocks over each of a succession of time intervals of selected duration. The background reads condition the memory cells prior to a first read operation associated with the host access commands."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Background reads to condition programmed semiconductor memory cells","description":"Method and apparatus for managing data in a semiconductor memory, such as but not limited to a three dimensional (3D) NAND flash memory array.
