COLUMN CORRECTION CIRCUIT FOR INTEGRATED CIRCUIT

摘要

PURPOSE: To provide a column repair circuit of a byte wide static RAM outputting a signal to a decoder through eight I/O pads without using a fuse by simultaneously selecting eight bit lines by means of an address. CONSTITUTION: This repair circuit is composed of an input/output selecting means, for selecting a bit line and a bit line complied with a malfunctioned address by inputting of a control signal (ϕREDY) and substituting an auxiliary bit line and an auxiliary bit line, and a decoder means, for transferring the information of the bit line and the bit line selected by inputting outputs SI01-SI08 of the input/output selecting means and addresses y0-y15 to a data bit line and a data bit line.
