Abstract

PURPOSE: To prevent the increment of a write threshold current based on the deflection of a holding current generated in case that memory cells constituted by I2L are assembled into an array, by a simple constitution where holding current supplying transistors are arranged dispersively in the array.
CONSTITUTION: In the memory where memory cells constituted by I2L are assembled into an array, n-bit, namely, n-number cells Ce1, Ce2...Cen are assembled into the array, and holding current supplying transistors Q7, Q7' and Q7" are arranged dispersibely, and dummy cell Ced required for the dummy function to shunt the write current is arranged outside cells Cel and Cen at the array end, and the current is shunted to dummy cell Ced when cell Cel or Cen is selected to flow the write current. Thus, since the holding current in the array is equalized, the incerment of the write threshold current based on the deflection of the holding current is reduced.
