Abstract

The disclosure prevents inconsistencies in a busy state between a master side memory chip and a slave side memory chip during a reset operation. A flash memory device () of the disclosure includes a master side memory chip () and at least one slave side memory chip (). A controller () of the master side memory chip () selects the master side memory chip or the slave side memory chip based on an externally inputted address, and performs a reset of the selected memory chip when a reset command is inputted. The data read from a specific area of a memory cell array of the master side memory chip is set in a register. The controller () controls a readout of the reset in a manner that time required for setting the data of the register is longer than time required for the reset of the selected memory chip.
