Abstract
A sensing circuit (30) for a random access memory (10) is disclosed. A CMOS sense amplifier (32) is coupled between bit line pairs which connected to I/O lines by a passgate (N4/N5). A pair of cross-coupled transistors (N6/N7) activated in synchronism with the passgate (N4/N5) is also disposed between the bit lines. The I/O line pairs each include a pair of cross coupled p-channel transistors (P4/P5). The combined action of the cross-coupled pairs (N6/N7) and (P4/P5) increase the sensing speed of the sensing circuit (30).
