MEMORY CONTROL DEVICE, SEMICONDUCTOR MEMORY DEVICE, MEMORY SYSTEM, AND MEMORY CONTROL METHOD

摘要

Provided is a technology to improve the safety of data. Specifically, in a memory system (100) provided with an information processing device (1) and a semiconductor memory device (2), the semiconductor memory device (2) is provided with an interface unit (61) which transmits data read out from a memory core (7) to the information processing device (1), in compliance with a plurality of protocols which have mutually different signal transmission/reception methods. A communication protocol selection unit (69) inputs a selection signal for selecting a specific communication protocol from the plurality of communication protocols on the basis of a switch command input from the information processing device (1), to the interface unit (61).
