Abstract: The shift register includes a number of stages, each having a data latch circuit (224,424) for storing a data bit, and a pointer latch circuit (222,422) for storing one bit of pointer information. A transfer circuit serially transfers data bits applied to a data input (DATA-IN) to the data latch circuits via the stages during a first operational mode. A pointer pre-move circuit serially transmits one or more bits of pointer information that form a pointer through the stages during a second operational mode, without disturbing data bits stored in the data latch circuits. Independent claims are included for a fuse programming circuit; a method of retaining pointer and data information in a shift register; and a method of sequentially programming a number of fuses.

Abstract: A circuit for the sequential programming of fuses (150.1-4) comprises latch circuits (130.1-4) holding data showing which fuse is to be burned through, with those not selected being asynchronous and those (150.1-4) for the burning circuit (140.1-4) burned with the burning voltage being synchronized. An Independent claim is also included for the following: (a) a DRAM comprising the above;and (b) sequential fuse processing programs for the above
