Semiconductor integrated circuit, ink cartridge, and inkjet recording device

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.”
