Ink cartridge having a storage device, method of receiving data which are to be written in a data storage unit from a host circuit, and system including a storage device which is electrically connectable to a host circuit

摘要

A storage device electrically connected to a host circuit includes a non-volatile data storage unit, a data receiving unit, determination unit, and a data transmitting unit. The data receiving unit receives data including first data which are to be written in a memory array and second data which are generated based on the first data from the host circuit. The determination unit determines consistency between the first data and the second data. The data transmitting unit transmits a result of the determination to the host circuit. In the case where an affirmative determination result is obtained by the determination unit, (1) in the case where writing data in the data storage unit is completed, the data transmitting unit transmits the affirmative determination result to the host circuit, and (2) in the case where the writing data in the data storage unit is not completed, the data transmitting unit does not transmit the affirmative determination result to the host circuit.
