Abstract
Exemplary methods, apparatuses, and systems include an adaptive pre-read manager for controlling pre-reads of the memory device. The adaptive pre-read manager receives a first set of data bits for programming to memory. The adaptive pre-read manager performing a first pass of programming including a first subset of data bits from the set of data bits. The adaptive pre-read manager compares a set of threshold operating differences to a set of differences between multiple operating conditions during the first pass of programming and current operating conditions. The adaptive pre-read manager performs an internal pre-read of the programmed first subset of data bits. The adaptive pre-read manager performs a second pass of programming using the internal pre-read and a second subset of data bits from the first set of data bits.
