Abstract
A method of searching for a boundary between a written portion and an unwritten portion of an open block may include performing a word line by word line binary search of a first physical area of the open block to identify a last written word line of the first physical area of the block, and subsequently, searching in at least a second physical area of the open block based on the last written word line of the first physical area of the block as identified by the binary search.
