Abstract
The invention provides a memory output circuit. The memory output circuit is capable of receiving bit line data and bit bar line data output by a memory cell array. In one embodiment, the memory output circuit comprises a pre-charge circuit, a pre-amplifier circuit, and a sense amplifier. The pre-charge circuit is capable of pre-charging a first node and a first inverse node wherein the bit line data and bit bar line data are respectively output to the first node and the first inverse node. The pre-amplifier circuit is capable of generating a second voltage on a second node and a second inverse voltage on a second inverse node according to a first voltage on the first node and a first inverse voltage on the first inverse node. The sense amplifier is capable of detecting the second voltage on the second node and the second inverse voltage on the second inverse node to generate a third voltage on a third node and a third inverse voltage on a third inverse node.
