Original Abstract Submitted
a memory device includes a content addressable memory (cam) block storing a plurality of stored search keys. the memory device further includes control logic that determines a first number of memory cells in at least one string of the cam block storing one of the plurality of stored search keys, the first number of memory cells storing a first logical value, and stores a calculated parity value representing the first number of memory cells in a page cache associated with the cam block. the control logic further reads stored parity data from one or more memory cells in the at least one string, the one or more memory cells connected to one or more additional wordlines in the cam block, and compares the calculated parity value to the stored parity data to determine whether an error is present in the one of the plurality of stored search keys in the cam block.
