The embodiment of the invention provides a flash memory detection method and device. The flash memory detection method comprises the following steps: determining a to-be-scanned area of a flash memory; determining a word line to be scanned in the area, and scanning the word line; the error correction unit corresponding to the word line is determined according to the scanning processing result, the reference voltage is determined through the error correction unit, the word line to be scanned is selected from the area to be scanned for scanning, scanning of all the area to be scanned is avoided, and the scanning time is shortened. 本说明书实施例提供闪存的检测方法以及装置，其中所述闪存的检测方法包括：确定闪存存储器的待扫描的区域；在所述区域中确定待扫描的字线，并对所述字线进行扫描处理；根据扫描处理结果确定与所述字线对应的纠错单元，并利用所述纠错单元确定参考电压，本方案通过在待扫描的区域中选择待扫描的字线进行扫描，从而避免了对待扫描的全部区域进行扫描，缩短了扫描时间。
