another patent win for alsc : High performance random access memory with multiple local I/O lines Abstract The present invention provides an apparatus and a method of reducing the time to drive the I/O lines by the sense amplifiers. In one embodiment of the present invention, local sense amplifier segments and associated local I/O lines are provided. The I/O lines are short in length and are connected to the sense amplifiers in the associated sense amplifier segments. The reduction in the length of the local I/O lines reduce the effective RC impedance of the I/O lines. Thus, the local sense amplifiers are smaller and drive the local I/O lines much faster. The present invention further provides global I/O lines connected to the local I/O lines. In a second embodiment of the present invention, the global I/O lines are driven by a second stage amplifier. In a third embodiment of the present invention, one global I/O line is provided for every local I/O line. Inventors: Kengeri; Subramani (Cupertino, CA); Reddy; Chitranjan N. (Los Altos Hills, CA).
