Abstract
An approach for testing an erasable programmable read-only memory (EPROM) cell for a threshold voltage is provided. A voltage lower than a source voltage that is associated with a read operation is applied to the gate of the EPROM cell. A signal is read out from the EPROM cell when the voltage is applied to the EPROM cell. The signal is used to calculate the threshold voltage of the EPROM cell.
