ABSTRACT:
A dynamic sense-refresh detector amplifier consists essentially of a cross coupled MOS transistor pair and two sets of load-refresh circuits which each include a capacitor and three MOS transistors. The load-refresh circuits eliminate the negative effect of threshold voltage losses on noise margin by allowing the memory cells from which information is read out and sensed to be refreshed to full 1 and 0 levels. The dynamic operation of the amplifier allows for relatively low power dissipation.
