Abstract
A transconductance test method implemented in a flash memory device detects memory cells with low transconductance and provides an output identifying memory cells, if any, having been classified as having a low transconductance (low g). In some embodiments, the transconductance test method implements multi-step testing using a pair of gate bias levels for each test step. Accurate detection of memory cells with low transconductance can be realized.
