Filed: 1992-03-19
Abstract: PURPOSE:To make the speed of the semiconductor memory much higher by a method wherein the delay time of a set/reset circuit is reduced. CONSTITUTION:In a semiconductor memory, transistors Q7, Q8 which perform a switching operation are constituted and installed between the following in a sense circuit constituted so as to include a pair of base-grounded transistors Q3, Q4: a pair of common sense lines 1, 1' which connect output terminals for a plurality of differential amplifiers; and a common current line 3 which takes out, in common, the selection current of a transistor for selection use in the differential amplifiers. One out of said transistors Q7, Q8 is turned on according to a set signal or a reset signal. Thereby, a set current or a reset current is made to flow to one out of the pair of base-grounded transistors Q3, Q4. When the Q7, Q8 are added to the high-speed sense circuit constituted so as to include the base-grounded transistors Q3, Q4 and a set and reset function is added, a set and reset circuit which is required in conventional cases is not required. As a result, the speed of a memory system can be made high by the portion of the delay time of a gate constituting the set/reset circuit.

CONSTITUTION:In a main surface layer 5 of a P-type Si substrate 1 N-type regions 20 and 21 are formed by ion implantation or diffusion, and then electrochemical reaction is appplied on the substrate 1 in a solution of hydrofluoric acid to prduce porous Si regions 22 in the substrate 1 under the condition that the substrate 1 is used as the anode. On this occasion, to prevent an anode forming current from passing into the regions 20 and 21, the level of the forming voltage is selected to a  value not higher than the diffusion voltage of PN-junctions between the substrate 1  and the regions 20, 21.
