Abstract
A semiconductor integrated circuit having a memory and an adjacent peripheral circuit generating minority carriers which can destroy data in a portion of the memory at low temperatures. The load resistance in the portion is made lower or the storage capacity is made higher in the portion than in the remainder of the memory so that at low temperatures data is not lost and the energy consumption of the circuit is not unduly increased.
Claims3
A semiconductor integrated circuit having a memory made up of individual elements having associated circuit values and a peripheral circuit generating minority carriers which influence some of the elements making up a portion of said memory wherein said elements are formed so that the values of at least one of said circuit elements are set in said portion different from the values in the remainder of said memory so that the effect of the influence is reduced in said portion so stored data, which would be otherwise lost if the values were the same as in the remainder of the memory, is not lost.
