ABSTRACT:
A novel driver circuit is disclosed that is used for driving a logic voltage sensed by a sensing amplifier of a memory onto a data line of the memory. The driver circuit is responsive to first sensing signals and second sensing signals that are delayed with respect to the first sensing signals. When the first and second sensing signals indicate that equalization is occuring in the sensing amplifier, the driver circuit latches the data line logic voltage on the data line without any false transitions or glitches occuring on the data line. In addition, the driver circuit becomes self biased when the first sensing signals indicate that sensing is occuring in the sensing amplifier but the second sensing signals indicate that equalization is still occuring. This is done to minimize the voltage swing in the driver circuit when the sensed logic voltage is driven onto the data line while both the first and second sensing signals indicate that sensing is occuring.
