Abstract: “A semiconductor integrated circuit can switch operation modes at proper timing and reduce a number of external terminals. By shifting to a low power consumption mode in response to an end of a printing operation by using an ink cartridge, an operation mode can be shifted without any effects on regular operations. In the low power consumption mode, a specified address can be initialized, resulting in an attempt for the reduction of power consumption. In the low power consumption mode, the power consumption can be reduced more by terminating operations of internal circuits including a sense amplifier, an address decoder, an output buffer, and a latch circuit. In addition, a chip-select terminal can be used to initialize circuit blocks and to shift to a stand-by mode, which results in a reduction of external terminals.

Abstract: Chip area and operating current is reduced in a chip having a write-inhibit circuit that uses a data-writing request signal WR and a write-control signal WRITE to inhibit data writing. By comparing a reference current Iref and a drive current ID, a current-mirror circuit CM can monitor the voltage of a power supply VDD. When the voltage of the power supply VDD is sufficiently high, the data-writing request signal WR is unchanged. Conversely, when the voltage of the power supply VDD is not sufficiently high, a transistor T6 producing reference-current ID and a buffer B2 cause the write-control signal to be low “L” irrespective of whether the data-writing request signal WR is at “H” or at “L”. Thus, miswriting can be prevented when the power-supply voltage decreases, since writing by the data-writing request signal WR is impossible.

Abstract: A delay unit is used to prevent writing errors due to residual charge on a bit line when changing rows to write to another bit line. By having a delay unit, a discharge time for discharging charge stored in a parasitic capacitance is reserved. An address is changed after the elapse of the reserved discharge time to assure that discharge is completed and writing errors do not occur. Charge can quickly build up in signal lines of a semiconductor integrated circuit having a charge unit for charging lines in a memory array of n rows and m columns. Write errors can therefore occur when charging a signal line corresponding to a next row after writing to all bits of one column is completed, and then sequentially writing to each bit in the column corresponding to the signal line charged by the charge unit.

Abstract: A monitoring section detects a write instruction to an open directory of a recording section in a control section from a write and read control section. When a falsification detection signal is inputted from the monitoring section to a control section, the control section controls a copy control section to read and copy information stored in backup directories to the open directory. This can prevent the open directory from being falsified. Since falsification is detected by detecting the write instruction, a high storage recording device and a high CPU capability are not required to detect the falsification.
