Abstract
A memory and a low offset clamp bias circuit thereof are provided. The low offset clamp bias circuit is adapted for any existing memory and is used for reducing the variation of a drain side voltage Vsupplied to a memory cell in a memory cell array area through the feedback mechanism formed by a clamp bias modulator and a constant voltage generator. Thereby, the accuracy in reading, writing, or erasing data in the memory can be improved.
