Abstract
In a trimming device, a counter circuit generates n-bit setting data for n-bit trimming data used to trim the trimmed circuit. A trimming data generation circuit includes trimming elements whose conductive parts are blown when an electrical signal flows therein, pull-up resistors connected to high potential sides of the trimming elements, switches connected to the high potential sides of the trimming elements, and buffers. The trimming data generation circuit switches the switches in accordance with a level of the setting data, and generates the trimming data that is inputted to the trimmed circuit, via the buffers, from nodes at which the pull-up resistors and the trimming elements are connected to each other.
