Abstract
A shared program circuit is provided for a plurality of memory circuits, and a select circuit is provided for selecting one of the memory circuits. The select circuit includes gate circuits for transmitting a program signal from the shared program circuit to the memory circuits, and a gate selector that activates one of the gate circuits. Thus, in a semiconductor integrated circuit device provided with a plurality of memory circuits, like an ASIC, chip area occupied by a program circuit for programming an address of a defective memory cell therein is reduced.
