<p>PURPOSE:To accelerate an operation by connecting a load circuit to permit a current of constant level to flow to a reference circuit. CONSTITUTION:The load circuit attached on the reference circuit is equipped with a memory cell 4 interposed between a transistor 3 and a memory cell MOR at the most upstream side, and memory cells 5, 6 arranged in series between the common node of the transistor 3 and the memory cell 4 and the ground potential. A power source potential VCC is applied to the gates of the memory cells 4-6 as constant potential. Therefore, a reference current of constant level can be always supplied to a sense amplifier, which accelerates decision for the inversion level of the sense amplifier. In such a way, the operation can be accelerated.</p> |
