Abstract:
A read path for reading data from a memory includes a sense amplifier having data (SAT) and data complement (SAC) output nodes and a latch. The latch includes an input tri-state inverter including first and second PMOS transistors connected between VDD and an intermediate node, and first and second NMOS transistors connected between VSS and the intermediate node. A gate connection of the first PMOS and NMOS transistors is connected to the SAT node; a gate connection of the second PMOS transistor is connected to a sense amplifier enable complement input; and a gate connection of the second NMOS transistor is connected to a sense amplifier enable input. The latch also includes an output driver with an input connected to the intermediate node and an output connected to a data output node. The latch thus has two gate delays between the SAT node and the data output node.
