Abstract

A read only memory element with polysilicon trench structure comprising: - a Si substrate on which there forms multiple source/drain electrodes with parallel arrangement, extending to first direction, and deep in substrate vertically; - a multiple polysilicon gate arranged in second direction, forming transistor structure by isolating source/drain electrode with gate oxide, where the area between two different source/drain under gate is channel in which the second direction is perpendicular intersection with the first direction.
