ABSTRACT:
Adjustment of operating parameters for a functional circuit is provided by fuse links (44) and (45). For a DRAM, the fuse links (44) control the various internal delays of a timing control generator (40) and fuse links (45) control the sensitivity of sense amplifiers by controlling an access control circuit (42). The sense amplifiers (14) determine the access parameters for a plurality of memory cell arrays (10) and (12). By varying the parameters of the sense amplifiers, the access parameters can be controlled by one adjustment on the central control circuitry.
