Abstract:

A method and system for pre-charging and biasing a latch-type sense amplifier are described. According to an embodiment of the invention, the data latch portion of the latch-type sense amplifier includes two cross-coupled inverters having two output nodes, and two input nodes. The input nodes of the data-latch are connected to a pair of complementary bit-lines via bias control transistors. The bias control transistors are to pre-charge the input nodes based on the voltage levels of the bit-lines so as to bias the voltage levels at the input nodes in a direction the input nodes will seek upon activation of the sense amplifier.
