    摘要： According to embodiments, a memory system includes a plurality of memory chips configuring banks, an instruction generator, and a memory controller. The instruction generator generates a plurality of instructions. The memory controller is configured to execute memory accesses to the banks based on the instructions. Each memory access comprises a first command sequence and a second command sequence. The first command sequence causes in-bank processing shortly subsequent to the first command. The second command sequence is executed subsequent to the in-bank processing. The memory controller executes successively a second command sequence to a first bank based on a first instruction and a first command sequence to the first bank based on a second instruction subsequent to the first instruction, and then starts a memory access to a second bank based on a third instruction while the first bank is executing the in-bank processing caused by the first command sequence.

    摘要： An optical fiber characteristic measuring device for automatically measuring, at successive measuring stages, various characteristics of optical fiber samples. Each measuring stage has optical system incident and emergent ends. An optical fiber sample is set in a carrier which moves from measuring stage to measuring stage. At each stage the set fiber sample is coupled to the incident and emergent ends of the stage and automatically subjected to the measurement to which the stage is dedicated. Bending units provide a desired degree of curvature to the fiber sample under test to control light propagation therein.

    摘要： A data/code conversion device receives confidential information, converts the confidential information into instruction codes for making a CPU provided in a semiconductor device perform its operation, and stores the instruction codes as dummy instruction codes in an external memory. One of the confidential information of which corresponding instruction code does not exist is converted into another instruction code as a dummy instruction code and stored, and correction data for reconstructing the confidential information from the instruction code is also stored in the external memory. In the semiconductor device, a decryption circuit for receiving the dummy instruction codes and the correction data stored in the external memory and performing decryption to obtain the confidential information is provided. Therefore, leakage of confidential information stored in the external memory can be reliably prevented with a relatively simple structure, so that the security level is increased.
