Patent ID: 8570823

Claim:
A sense amplifier comprising: a pair of data lines comprising a first data line and a second data line; a first pair of transistors of a predetermined type, the first pair of transistors comprising a first transistor and a second transistor, a gate terminal of the first transistor coupled with a drain terminal of the second transistor, and a gate terminal of the second transistor coupled with a drain terminal of the first transistor; a pair of nodes comprising a first node corresponding to the drain terminal of the first transistor and a second node corresponding to the drain terminal of the second transistor, and the pair of nodes arranged for providing read data for the sense amplifier; a second pair of transistors of the predetermined type, each of the second pair of transistors having a drain terminal coupled to a corresponding source terminal of the first pair of transistors and having a gate directly coupled to a corresponding one of the pair of data lines; and a pair of transferring devices comprising a first transferring device coupled between the first data line and the first node and a second transferring device coupled between the second data line and the second node; wherein in a read cycle, the first transferring device is configured to transfer data on the first data line directly to the first node; and the second transferring device is configured to transfer data on the second data line directly to the second node.
