Abstract
A repair information storage circuit may include a fuse block, a controller, and a fuse latch array. The fuse block provides a boot-up enable signal and repair information. The controller generates a voltage control signal in response to the boot-up enable signal. The fuse latch array stores repair information provided from the fuse block. The voltage control signal, which is used as a bulk bias of a transistor formed in the fuse latch array, is adjustable.
