ERASABLE BLOCK SEGMENTATION FOR MEMORY

摘要

Various embodiments comprise apparatuses such as those having a block of memory divided into sub-blocks that share a common data line. Each of the sub-blocks of the block of memory corresponds to a respective one of a number of segmented sources. Each of the segmented sources is electrically isolated from the other segmented sources of the block of memory. Additional apparatuses and methods of operation are described.
