Abstract
An embodiment of the present invention includes a tag array, a valid vector, and a detector. The tag array stores N tag entries. Each of the N tag entries contains a one-hot tag having K bits. Each of the K bits of the one-hot tag corresponds to a translation look-aside buffer (TLB) entry in a TLB array having K TLB entries. The valid vector stores N valid entries corresponding to the N tag entries. The detector detects an error when a tag entry is read out upon a fetch read operation.
