Abstract
A method for storing data includes determining, using a first match line, that a match word satisfies a first content addressable memory (CAM) word stored in a CAM array, wherein the CAM array is configured to store a second CAM word that matches the first CAM word. The method further includes determining that a first parity bit associated with the first CAM word matches a first parity of the first CAM word. The method further includes, in response to determining that the first parity bit associated with the first CAM word matches the first parity determining, using the first match line, a first random access memory (RAM) word stored in a RAM array and outputting the first RAM word.
