Abstract
The speed and stability of a 4T static RAM cell (10) comprising cross-coupled inverters with two driver transistors, (18, 20) and two pass-gate transistors (14,16) are improved by replacing the driver transistors with a modified driver element (33, 35), comprising at least two transistors (18, 18') having common gates and common sources and with a resistor (42) connecting the drains.
