Abstract
A memory controller includes, in one embodiment, a memory interface and a controller circuit. The memory interface is configured to interface with a memory having a plurality of wordlines. The controller circuit is configured to program, with foggy-fine programming, a first portion of the plurality of wordlines to store first program data, program, with the foggy-fine programming, one or more wordlines of the plurality of wordlines in a non-fine state, the one or more wordlines neighboring the first portion, and program, with the foggy-fine programming, a second portion of the plurality of wordlines to store second program data, the second portion neighboring the one or more wordlines.
