Abstract

A storage register for use with a circuit for intercepting and replacing faulty cells where the storage register comprises a shift register with a latch structure as an integral part of thatregister to enable it to store data and present it to a comparator circuit. The shift register comprising a first stage and a second stage inverter circuit such that on application of the hold controlling signal the integrity of the data at the output of the second stage inverter is retained.
