Abstract
The present invention relates to a circuit for generating a reference voltage trimmed by an anti-fuse programming, comprising: reference voltage generation means for providing a reference voltage having a predetermined level; decoding means generating for decoding signals in order to trim a level of said reference voltage according the anti-fuse programming; and voltage trimming means for dividing said reference voltage using resistance variable in response to said decoding signals supplied from said decoding means, thereby trimming the level of said reference voltage. The present invention programs the anti-fuses on the basis of the voltage signals applied through the bonding pads to generate the decoding signals, and thereafter divide the reference voltage using the resistance variable in response to the decoding signals, thereby capable of minutely trimming the level of the reference voltage from the reference voltage generation means.
