    摘要: An ECC control apparatus is to be connected between a host and a memory. The apparatus comprises a first input/output circuit, a detecting circuit, a code-generating circuit, a code-inserting circuit, a second input/output circuit. The first input/output circuit inputs and outputs data to and from the host. The detecting circuit detects a protected-data region and a redundant region of write data input to the first input/output circuit and having a predetermined data length. The code-generating circuit generates an error-correction code for correcting errors in data stored in the protected-data region. The code-inserting circuit inserts the error-correction code in the redundant region. The second input/output circuit inputs and outputs data to and from the memory.

    摘要: A processor boot-up controller includes: a volatile memory connected to a nonvolatile memory; a selector, which transfers boot-up codes to the volatile memory from the nonvolatile memory; a controller for the nonvolatile memory configured from a boot-up control sequencer, which transmits CPU read-in data to the CPU and brings the CPU into a wait state until boot-up code transfer completes; and an error detection and correction unit connected to the external CPU and the nonvolatile memory. The processor boot-up controls the CPU by reading data from the nonvolatile memory. The processor enables the CPU to access a SRAM in the shortest time in sync with the SRAM's ready timing, resulting in a reduction of average system boot-up time. An information processing system can use the controller for example for a nonvolatile memory, a microprocessor boot-up controller, and multi-valued nonvolatile memory.

    摘要: This non-volatile memory system includes: a non-volatile memory; and a memory controller controlling read and write of the non-volatile memory. Access control of the non-volatile memory system is performed in accordance with a logical address, using an address translation table within the memory controller that is updated in association with data write and that indicates a correlation between logical addresses provided by a host and physical addresses of the non-volatile memory. The non-volatile memory system is also configured to be able to set a system configuration and function in relation to the host.

    摘要: A communication line is connected to first and second chips, and held at a first signal level. A monitor circuit changes a signal level of the communication line from the first signal to a second signal level while one of the first and second chips uses a current larger than a reference current. When the signal level of the communication line is the second signal level, the other of the first and second chips is controlled to a wait state that does not transfer to an operating state of using a current larger than the reference current.
