Title: Semiconductor storage device
Inventor: KOBAYASHI TOMOHIRO
IPC: G11C29/00
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To reduce a delay by a data bus thereby enabling high-speed accessing and improve recovery efficiency by dividing a spare cell part for each column I/O part and arranging near a data input and output circuit. SOLUTION: A spare part is divided for each I/O part into I/O parts 0 to 8-SPR. The I/O parts 0 to 8-SPR are arranged dispersively among normal cell parts S1-S16 an connected via sense amplifiers 20 to global data liens 300-308 connected to input and output lines 400-408 respectively. When a memory cell of any one of sections S1-S16 of the normal cell parts fails, each I/O part is replaced with the I/O part of the spare cell part. A failing address and an external address are compared by a program fuse if the failing cell is accessed and, a spare memory cell is accessed in accordance with a detection signal generated in consequence of the comparison. At this time, the I/O parts of the spare cell part are arranged discursively in the vicinity of the input and output line 400, thus enabling high-speed reading.

Abstract: PROBLEM TO BE SOLVED: To provide a monolithic ink jet printer head ensuring a good print quality stably by preventing generation of a bubble through electrolysis of ink. SOLUTION: The ink jet printer head comprises a drive circuit 23 of diffusion layer, an oxide film 39, a heater layer 24 (heating part 24a, extension part 24b), an adhesion layer 41, an electrode layer (common electrode 25, discrete wiring electrode 26), an insulation layer 42, a barrier wall (29-1, 29-2, 29-3), and an orifice plate 31 formed sequentially on the upper surface of a chip substrate 22. An ejection nozzle 34 is made in the orifice plate 31 and an ink channel (ink supply path 27, ink supply hole 28) is made in a chip substrate 22.  Since electrical contact of a common electrode 25, the discrete wiring electrode 26 and the heating part 24a of the heater layer with ink is blocked by means of an insulation layer 42, current flow from the electrode to the exposed silicon part of the ink channel is blocked even if a voltage for driving the heating part 24a is applied from an external power supply through electrodes 25, 26 by means of a drive circuit 23. Consequently, electrochemical change of ink is inhibited thus preventing generation of a bubble.
