SEMICONDUCTOR DEVICE INCLUDING A FLAG CELL CAPABLE OF IMPROVING THE EFFICIENCY OF A WRITE VERIFICATION OPERATION AND A READ OPERATION FOR A FLAG CELL GROUP

摘要

PURPOSE: A semiconductor device is provided to integrate the semiconductor device by transmitting a read result of a flag cell group as a signal of a single bit.;CONSTITUTION: A page buffer group(20) performs a write verification operation and a read operation for a flag cell group(10). A comparing unit(100) generates a flag state signal according to the output current of the page buffer group and a state reference code written in a state reference register(200) in the write verification operation for the flag cell group, and generates a flag determination signal according to the output current of the page buffer group and a determination reference code written in a determination reference register(300) in the read operation for the flag cell group.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Flag cell group; (20) Page buffer group; (200) State reference register; (300) Determination reference register; (400) Switch unit; (500) Comparing unit
