Abstract
The present invention concerns a circuit and method for improving the data access times across boundary reads between cascaded buffers, such as FIFOs, that are connected to a common data output bus. The circuit allows read accesses within a cascaded buffer system to have similar access speeds, i.e., a boundary read is not noticeably slower or faster than any other non-boundary read access from an individual buffer in the system. The circuit may not adversely affect the data sheet or operating system parameters, and imposes minimal chip real estate constraints.
