摘要:
A technique to determine whether multiple memory cells are programmed or erased. After a program or erase operation, respective program or erase verify operations are performed. A logical gate is coupled to measure the state of each memory cell. When all memory cells selected to be programmed or erased are programmed or erased then the output of the logical gate indicates successful program or erase verify. Thus, by using a single logical gate coupled to measure the states of multiple memory cells, only the output of the logical gate need be measured to determine successful program or erase verification of multiple memory cells.
