Abstract
A programming control circuit programs a memory cell in accordance to a programming signal value that can be varied by a test equipment. The programming control circuit comprises a signal storage device, a signal output circuit, and a verification circuit. The signal storage device stores the programming signal value. The test equipment can be coupled to the signal storage device to write the programming signal value into the signal storage device. The signal output circuit is coupled to the signal storage device to receive the programming signal value. The signal output circuit converts the programming signal value into a programming signal and outputs the programming signal to the memory cell. The verification circuit determines whether the memory cell is successfully programmed. If the memory cell is not successfully programmed, the programming control circuit increases the programming signal value.
