ABSTRACT:
The invention comprises an improved bipolar memory device having enhanced protection against the effects of alpha particles comprising at least one memory cell having a buried layer forming at least a portion of the collector of one of the transistors in the memory cell, said buried layer being located sufficiently close to a base layer in only the memory portion of the device to provide a sufficiently high capacitance between said buried layer and said base layer to prevent the occurrence of a soft error caused by an alpha particle striking the structure without interfering with the speed of the device.
