Security memory access method and apparatus

摘要

Various embodiments comprise apparatuses and methods to allow access to a memory device by an external device. A method includes receiving, at the memory device, a request from the external device to access a storage area of the memory device and performing an unlock procedure of the storage area. The unlock procedure includes sending a first code from the memory device to the external device, and receiving a second code at the memory device from the external device. The second code is to be generated by a first encryption process performed on the first code to obtain the second code. The storage area is temporarily unlocked to allow the external device to access the storage area based on a determination that the received second code has a predetermined relationship to the first code. Additional apparatuses and methods are described.
