MEMORY DEVICES, AND SYSTEMS AND METHODS FOR VERIFYING SECURE DATA STORAGE

摘要

A memory device includes an input/output (I/O) interface, a secure logic for receiving a storage verifying command including an expected value of secure data via the I/O interface, an I/O logic for receiving an input request for inputting user data into the memory device and/or an output request for outputting user data therefrom and perform one of the input request and/or the output request, and a memory unit including a secure area, accessible by the secure logic, for storing the secure data and a normal area, accessible by the I/O logic, for storing the user data. The secure logic reads the secure data from the secure area in response to the input of the storage verifying command and outputs a storage verifying result to the external device, without outputting the secure data to the external device, according to whether the secure data expected value is identical with the secure data.

1. A memory device comprising:
an input/output (I/O) interface; a secure logic configured to receive a storage verifying command including an expected value of secure data, from an external device via the I/O interface; an I/O logic configured to
receive a request for at least one of inputting user data into the memory device and outputting user data from the memory device via the I/O interface, andperform at least one of the inputting and the outputting based on the request; and a memory unit including
a secure area for storing the secure data, the secure area being accessible by the secure logic, anda normal area for storing the user data, the normal area being accessible by the I/O logic, wherein the secure logic is configured toread the secure data from the secure area in response to the input of the storage verifying command, andoutput a storage verifying result to the external device, without outputting the secure data to the external device, according to whether the secure data expected value is identical to the secure data.
