SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

摘要

In a semiconductor integrated circuit device constituting a memory cell array which is formed by integrated injection logic memory cells, the cells are arranged in matrix form, bit lines (Bo, B1) being connected to the memory cells in the column direction and word lines (W+W-) being connected to the memory cells in the row direction; one word line (W-) is formed by a semiconductor bulk. Dummy cells (DC), which include a shunt circuit for shunting a write current of the memory cell and a hold circuit for supplying a hold current to the memory cell are arranged in each line of the memory array.
