Abstract
A method for memory block management includes identifying a first group of bit lines corresponding to memory blocks of a 3-dimensional memory array. The method also includes biasing the first group of bit lines to a first voltage using respective bit line biasing transistors. The method also includes identifying, for each memory block, respective sub-memory blocks corresponding to word lines of each memory block that intersect the first group of bit lines. The method also includes logically grouping memory addresses of memory cells for each respective sub-memory block associated with the first group of bit lines.
