摘要： A technique allowing an improvement in the confidentiality of information stored in a memory device. A memory controller includes a key generation part that newly generates key information for use in encryption and decryption of information at every predetermined timing, and a data conversion circuit that encrypts information to be outputted to a memory device based on the information and decrypts encrypted information inputted from the memory device based on the key information. In the data conversion circuit, each time the key generation part generates new key information, key information is updated so as to set the new key information as the key information.

摘要： A semiconductor memory includes a memory control section and a memory core section. A command judgment circuit in the memory control section changes the operating mode of the semiconductor memory in response to a command sent from a controller of an information processing apparatus. In a first mode, a decryption process is performed in a command decryption circuit, and data outputted from the memory core section is not scrambled. In a second mode, the decryption process is not performed in the command decryption circuit, and the command outputted from the memory core section is scrambled.

摘要： Lactic acid with high optical purity that has not previously been achieved is produced.It has been found that the optical purity of lactic acid is reduced as the racemization reaction of lactic acid proceeds when lactic acid coexists with glycerol. By reducing the amount of glycerol prior to concentrating lactic acid by heating, the optical purity of lactic acid after concentration by heating can be maintained at a high level.
