SEMICONDUCTOR MEMORY DEVICE EQUIPPED WITH ACTIVE LOAD CIRCUIT, AND ITS RELATED METHOD

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor memory device equipped with an active load circuit. SOLUTION: This semiconductor memory device is provided with a memory cell array including many memory cells, a bit line sense amplifier for sense-amplifying data output from the memory cell of the memory cell array to a bit line and supplying the sense-amplified data to a data line and a complementary data line, and an active load circuit including a first load element electrically connected between the data line and a first power source and a first load element electrically connected between the complementary load element and the first power source. The electric resistance of the first load element is varied in response to the voltage level of the data line, and the electric resistance of the second load element is varied in response to the voltage level of the complementary data line.
