Title: Semiconductor memory circuit
Inventor: EKUNI MASANORI
IPC: H01L27/10
Filed: 1990-10-22
Abstract: PURPOSE:To detect a constant substrate potential even if the threshold voltage of a transistor is varied by connecting a fuse in series between a plurality of transistor rows for sensing substrate potentials and the output terminal of a substrate potential sense signal. CONSTITUTION:Threshold voltages VTH of transistors are measured at the time of probe-inspecting a semiconductor memory, and a predetermined fuse of fuses F1 - F3 is melted to select a transistor row nearest to an arbitrary substrate potential VBB of substrate potentials VBB1 - VBB3. For example, if a transistor row A2 can sense an optimum VBB, the fuses F1 and F3 are melted by a laser cutting technique to select only the row A2, and a constant substrate potential can be sensed even if the threshold voltage of the transistor is varied due to a variation in a process.
