Abstract: PURPOSE:To increase the mechanical strength of a superconductive material enveloped by a carbon material by using the PAN production method. CONSTITUTION:The production method of the PAN fiber is used when a carbon material is formed into a fiber. A superconductive material is molded into the carbon material 1 as a raw material, it is formed into an endless filament or a strand in the procedure to produce the PAN fiber. Next, it is slightly oxidized in the air at about 200 deg.C, a blackened carbon fiber raw material is heated in N2 at 1000-1500 deg.C and carbonized. It is heated to 2500 deg.C for the high-elasticity type. When carbon material superconductive material composite electric wires thus obtained are assembled into a knitted wire, the mechanical strength is extremely increased, and it can be mass-produced.

IPC: G11C29/12
Filed: 1990-03-30
Abstract: PURPOSE:To improve the reliability of selecting a chip by providing a means impressing a prescribed bias potential on a common source line at a data read mode and checking the threshold of a selected memory cell. CONSTITUTION:A bias is impressed on the common source line SS fixed to a regular ground potential by an external power source or an internal power source. At the time of selecting the chip, the positive bias is impressed on the common source line SS with a control gate 14 as 0V instead of impressing the negative bias on the control gate of the memory cell which is selected at the data read mode. Consequently, it becomes equal to a value when the negative bias is impressed on the control gate 14 and the distribution of the threshold of the memory cell in an eliminated state can be measured. Thus, the reliability of selecting the chip of a non-volatile semiconductor storage device (EEPROM) which can electrically be rewritten can be improved.
