Abstract: The command decoder decodes a command signal to generate a command control signal. The mask circuit receives the command control signal to recognize the operating state of the memory core thereafter, and activates a mask signal when the command signal to be supplied anew is unacceptable. The control circuit disables an operation of the memory core corresponding to the command control signal when the mask signal is activated. Illegal commands are decided by the mask circuit alone. On this account, the control circuit need not be provided with a circuit for individually determining commands as illegal in accordance with actual operating states. Therefore, using the mask circuit makes it possible to prevent malfunctions resulting from illegal commands with facility and reliability. The intrinsic functions of the control circuit have only to be verified at the time of design and circuit modifications, which results in improving design efficiency.

Abstract: A semiconductor memory device that performs a flash write operation without increasing the circuit area. Column selection lines CL0-CL7 extend parallel to word lines at locations corresponding to where column gates are formed. During a flash write mode, the subcolumn decoder 14 simultaneously selects the column selection lines. This writes cell information to every memory cell connected to the selected word line.

Abstract: In performing a read operation or a write operation in a memory cell, a row control circuit is first operated to activate a word line. Subsequently, a command control circuit receives a column operation command in synchronization with a clock signal so as to operate a column control circuit. Here, under the control of a timing adjusting circuit, the column control circuit starts operating a predetermined delay time after the reception of the column operation command. By delaying the operation of the column control circuit, the read operation or the write operation in the memory cell can be performed at the optimum timing corresponding to the operating timing of an internal circuit independent of the cycle of the clock signal. As a result, the number of times in receiving commands per unit time can be increased to enhance the bus occupation rate of data.

Abstract: A resin-coated Al—Zn alloy coated steel sheet is excellent in formability, resistance to chromium dissolution, corrosion resistance, alkali resistance, and paintability, and produced by the following method. That is, a silane coupling agent having amino group, chromium ion and at least one alcohol selected from the group consisting of trihydric alcohol and dihydric alcohol having the number of carbon of 2 to 3 are compounded into an acrylic polymer resin emulsion including carboxyl group and glycidyl group, and having an acid value of 10 to 60. A pH of the resultant mixture is adjusted within a range of 7 to 9 to obtain a chromate containing resin composition. The chromate containing resin composition is applied on an Al—Zn alloy coated steel sheet as a substrate, and then dried to obtain a resin film on the substrate. A compounding amount of the silane coupling agent is within a range of 0.5 to 3.0 wt % with respect to a resin solid component of the acrylic polymer resin emulsion.
