Abstract:
A semiconductor storage device achieving stabilization of an operating voltage of a selected memory chip. A flash memory device of the disclosure includes a master chip and at least one slave chip. A voltage output portion of a charge pump circuit of the master chip is connected to an internal pad of the master chip, and a voltage output portion of a charge pump circuit of the slave chip is connected to an internal pad of the slave chip, the internal pad of the master chip and the internal pad of the slave chip are connected by a wire. When the mater chip is operated, the charge pump circuit of the master chip is turned off, the charge pump circuit of the slave chip is turned on, and a voltage generated by the charge pump circuit of the slave chip is supplied to the master chip.
