Non-volatile memory device e.g. flash memory device for verifying data programmed or erased in pipelining sequence, verifies programmed or erased data stored in data storage unit while data detector is sensing new programmed or erased data

摘要

A data detection circuit senses data of a selected memory cell of a memory cell array after programming or erasing operation of the selected memory. A verifier circuit verifies programmed or erased data stored in a data storage unit while the data detector is sensing new programmed or erased data. An independent claim is also included for method of verifying data in non-volatile memory device.
