Title: Semiconductor storage device
Inventor: MORIKAWA KOICHI
IPC: G11C11/417
Filed: 1995-03-20
Abstract: PURPOSE: To reduce power consumption at the time of the write operation of the data of a semiconductor storage device. CONSTITUTION: Data are written into a memory cell MC by lowering the potential of one bit line of a bit line pair (Bnj, -Bnj) pre-charged previously. A detector Sj outputs a detecting signal in response to the reaching of a bit line dBj to fixed potential at the time of the write operation. Accordingly, the potential of a bit line Bj exceeds potential, where writing is made possible into the memory cell, and is not lowered to a value more than required.
