Memory cell array latchup prevention

Abstract

A memory including current-limiting devices and methods of operating the same to prevent a spread of soft errors along rows in an array of memory cells in the memory are provided. In one embodiment, the method begins with providing a memory comprising an array of a plurality of memory cells arranged in rows and columns, wherein each of the columns is coupled to a supply voltage through one of a plurality of current-limiting devices, Next, each of the plurality of current-limiting devices are configured to limit current through each of the columns so that current through a memory cell in a row of the column due to a soft error rate event does not result in a lateral spread of soft errors to memory cells in the row in an adjacent column. Other embodiments are also provided.
