DATA SENSING DEVICE OF FLASH MEMORY

摘要

PURPOSE: A data sensing device of a flash memory is provided to reduce an error rate by adjusting a load value of a reference cell. CONSTITUTION: In a data sensing device of a flash memory, a main cell load part(35) adjusts a load of a main cell bias part which applies a bias to a main cell. A reference cell load part(30) adjusts a load of a reference cell bias part which applies a bias to a reference cell. A load rate setting part(40) sets a load value of the reference cell load part according to a verification state and a normal state. A load rate adjusting part(60) adjusts a load value of the reference cell load part. A sense amplifier(50) senses a differential between currents flowing into the reference cell load part and currents flowing into the main cell bias part.
