SEMICONDUCTOR INTEGRATED CIRCUIT, INK CARTRIDGE HAVING THIS SEMICONDUCTOR INTEGRATED CIRCUIT, AND INK JET RECORDING DEVICE MOUNTED WITH THIS INK CARTRIDGE

摘要

A signal line is charged in a short time and surely in a semiconductor integrated circuit including a charge unit for charging a signal line corresponding to each 1 row in response to an input of a writing instruction for each bit of a memory cell arranged in n rows by m columns (where n and m are natural numbers and so forth) and charging a signal line corresponding to a next row after writing on all bits for one column is completed, and performing writing on each 1 bit sequentially in each of bits for 1 column corresponding to the signal line charged by the charge unit. By having a delay unit, a time for discharging charges charged in a parasitic capacity is reserved. An address is changed after the discharge is completed so that wrong writing does not occur. <IMAGE>
