Abstract
A memory cell structure has a pair of cross-coupled inverters, each inverter having first and second MOS series coupled transistors. Each of the second inverter transistors has a source disposed near the periphery of the cell, a drain disposed closer to the center of the cell than the source thereof, and a channel region disposed between the source and drain. The channel region shields the sensitive drain from radiation generated photocurrents, thereby minimizing the chance of a change in logic state during radiation.
