Abstract
Voltage is increased on a wordline signal. The wordline signal is applied to a programmed FET and an unprogrammed FET of a memory cell. The programmed FET has a higher threshold voltage than the unprogrammed FET. The programmed FET is connected to a first bitline and the unprogrammed FET is connected to a second bitline. It is determined that the second bitline has reached a threshold voltage. In response to determining the second bitline has reached the threshold voltage, the first bitline is pulled towards ground. A signal is output based on a low voltage of the first bitline and a high voltage of the second bitline.
