Abstract
A memory array has a first memory cell with a plurality of transistors connected so as to restore a data value to a node of the memory cell to an initial value following an event upsetting the initial value. A first portion of the plurality of transistors is in a first cell portion and a second portion of the plurality of transistors is in a second cell portion. A second memory cell has a third cell portion and a fourth cell portion. The third cell portion is between the first cell portion and the second cell portion and adjacent to each of the first cell portion and the second cell portion. In a particular embodiment, the memory cell is a single-event-upset ('SEU') tolerant memory cell and the first and second cell portions are each a half cell of a sixteen transistor memory cell.
