Abstract
A BIST circuit that can be placed in a halt mode has been provided. During halt, the operation of the BIST circuit is stopped when an error has been detected thereby allowing for faster location of the error. The BIST circuit also includes a memory access mode which allows for independent read or write access to a predetermined address of a storage device under test.
