Abstract
A semiconductor integrated circuit device has an array of memory cells formed by integrated injection logic. A desired number of dummy cells are provided at both ends of each line of the array, so that a write current, which flows when the memory cell near the dummy cell is selected, is shunted by the dummy cell, thereby the currents which flow in the memory cells in the line of the memory array are equalized.
