ABSTRACT:
A row address strobe signal input buffer and method for converting an external input row address strobe signal to an internal signal and protecting the internal signal from background noise in the circuit. In the preferred embodiment the invention level-shifts the row address strobe signal to an internal signal of CMOS signal level. It then latches the internal signal to its current state and opens a transmission gate cutting off the internal signal from the external row address strobe signal. This prevents glitches in the internal signal due to noise in the circuit introduced due to the external row address strobe signal being of a TTL level. The gate remains open for a delayed period of time, the delay determined by a delay circuit or by the length of a pulse from a pulse generator. After the delay period, the gate is closed, restoring the signal connection between the external row address signal and the internal signal.
