Abstract:
1. A memory device connectable with a host apparatus and adapted to operate with power supplied from the host apparatus, comprising: external terminals for connecting with the host apparatus; a non-volatile memory chip capable of storing data; an IC chip capable of storing data; and a controller chip connected with the external terminals, the non-volatile memory chip and the IC chip, wherein: the non-volatile memory chip, the IC chip and the controller chip are discrete chips, responsive to a command from the host apparatus, the controller chip writes data inputted from the host apparatus into the non-volatile memory chip via the external terminals, and responsive to a command from the host apparatus, the controller chip transfers data read from the non-volatile memory chip to the host apparatus via the external terminals, responsive to a command from the host apparatus, the controller chip requests the IC chip to do processing, and the non-volatile memory chip is capable of storing data inputted from the host apparatus via the external terminals, and information necessary for operating the IC chip.
