Abstract
A ROM (read only memory) is disclosed. For via-ROMs, an isolation transistor is used to isolate adjacent pairs of memory devices instead of the more conventional field oxide isolation. The gate of the isolation transistor is grounded, insuring that conduction does not take place. For a GASAD ROM, a field oxide isolation is used.
