Title: Semiconductor memory device
Inventor: YOSHIKAWA SADAO
IPC: G11C29/12
Filed: 1991-10-29
Abstract: PURPOSE:To prevent a defect of cell transistors TRs constituting a memory cell from affecting an influence upon a memory cell block. CONSTITUTION:Cell TRs S1 to S4 are connected in series to form memory cell arrays L1 to L4, and these memory cell arrays L1 to L4 are connected in parallel to constitute the memory cell block. Enhancement or depletion TRs are used as cell TRs S1 to S4; and in the case of the memory cell array L2 where all cell TRs S1 to S4 are enhancement TRs, the open state is set so that a bit line 2 is not pulled down to the ground potential even if all cell TRs S1 to S4 are made conductive. Thus, cell TRs S1 to S4 are judged to be turned off independently of turning-on/off of cell TRs S1 to S4 of the memory cell array L2.

IPC: H01M4/50
Filed: 1990-10-22
Abstract: PURPOSE: To eliminate the need of stringent thermal treatment for a molded cathode, and use an electrolyte solvent having both of a decomposing property and a gas generating property by mixing a cathode active material having an active surface functional group with an inorganic additive, heating the inorganic additive so as to cause the partial deactivation of cathode active surface and then forming the cathode.

Then, the resulting mixture is treated by applying heat, for example, whenever necessary, so as to prevent the occurrence of reaction on the substantially entire surface of the active cathode, and cause the partial deactivation of the surface. In this case, the quantity of the inorganic additive should preferably exist in the cathode approximately by 5wt.% as a maximum. Also, nitrates such as lithium nitrate and calcium nitrate, and metal salts such as nitrates of other alkali and alkaline earth metals can be mentioned as the inorganic additive.  According to this construction, stringent thermal treatment for a molded cathode is not required, and an electrolyte solvent having both decomposing and gas generating properties can be used.
