Abstract
An apparatus can comprise a memory array comprising a plurality of strings of memory cells. A first string of the plurality of strings can comprises: a first group of memory cells coupled to a first group of access lines and corresponding to a first erase block; and a second group of memory cells coupled to a second group of access lines and corresponding to a second erase block. A controller is coupled to the memory array and configured to, in order to selectively erase the second erase block independently of the first erase block: apply a voltage having a first value to a sense line coupled to the plurality of strings; apply a voltage having a second value less than the first value to the first group of access lines; and apply a voltage having a third value less than the second value to the second group of access lines.
