ABSTRACT:
A method for verifying that a flash EEPROM memory device has reached a programmed state including the steps of providing a programming pulse of a preselected level and unspecified duration to the device, monitoring the current through the device as the programming pulse is applied, and providing a signal to terminate the programming pulse when the current through the device reaches a state equivalent to that through a programmed device.
