Abstract
This invention relates to a token passing network, called a Universal BIST Scheduler (UBS), and a method for scheduling BISTed memory elements based on: executing BIST in multiple stages in order to optimize the efficiency of continuous processing and to apply a single waiting period to multiple SBRIC_RSs where, for example, BIST includes retention testing; dividing resource controllers or SBRIC_RSs corresponding to one or more RSB elements into a matrix such that each SBRIC_RS executes the BIST of its memory elements concurrently and/or successively depending on the SBRIC_RS's position in the matrix; and passing a token to initiate processing of a set of SBRIC_RSs in the matrix through a level signal rather than a pulse signal in order to ensure that the signal is not lost.
