Abstract
An improved shield for an EPROM cell comprising a first and second metalization cover sections along with upstanding elements is disclosed. The invented shield protects selected EPROM cells from exposure to radiation in redundant memory applications. The shielding structure is designed such that radiation incident upon the memory only reaches the cell after traveling a circuitous route defined by the upstanding members. The improvement also increases the reliability of the memory while adding a degree of flexibility to the layout of the cell.
