In a static random access memory (SRAM) device having a hierarchical bit line architecture, a local sense amplifier (SA) circuit includes P-channel transistors which precharge local bit lines connected to memory cells, P-channel transistors each having a gate connected to a corresponding one of the local bit lines and a drain connected to a corresponding one of global bit lines, and N-channel transistors each having a gate connected to a corresponding one of the global bit lines and a drain connected to a corresponding one of the local bit lines. As a result, restore operation to a non-selected memory cell during write operation can be achieved without the need of a fine timing control, the speed of read operation by a feedback function can be increased, and the area can be reduced.
