Summary:Methods, systems, and devices for error control for content-addressable memory (CAM) are described. A CAM may store bit vectors as a set of subvectors, which each subvector stored in an independent aspect of the CAM, such as in a separate column or array of memory cells within the CAM. The CAM may similarly segment a queried input bit vector and identify, for each resulting input subvector, whether a matching subvector is stored by the CAM. The CAM may identify a match for the input bit vector when the number of matching subvectors satisfies a threshold. The CAM may validate a match based on comparing a stored bit vector corresponding to the identified match to the input bit vector. The stored bit vector may undergo error correction and may be stored in the CAM or another memory array, such as a dynamic random access memory (DRAM) array.
